Multiplexers are used in communication systems to increase the amount of data that can be sent over a network within a certain amount of time and bandwidth.

The multiplexer MUX functions as a multi-input and single-output switch. The selection of the input is done using select lines.

You can find the detailed working and schematic representation of a multiplexer here. Well, in Verilog hardware descriptive language, we have four main abstraction layers or modeling styles.

Now before jumping to the coding section, a brief description of each modeling style has been presented before you.

MUX – Digital Multiplexer | Types, Construction & Applications

As the name suggests, this style of modeling will include primitive gates that are predefined in Verilog. The prerequisite for this style is knowing the basic logic diagram of the digital circuit that you wish to code. The input signals are D0 and D1. S is the select line with Y as its output. We can orally solve for the expression of the output that comes out to be:.

For the gate level, we will first declare the module for 2: 1 MUX, followed by the input-output signals. The order of mentioning output and input variables is crucial here, the output variable is written first in the bracket, then the input ones. The module is a keyword here. Y is the output and D0D1 and S being input are written after.

Next comes the declaration of input, output, and intermediate signals. You might have noticed that other modeling styles include the declaration of variables along-with their respective data- types. Next comes the instantiation part for gates. For example for not gate, Sbar is the output and S is the input. This is the design abstraction, which shows the internal circuitry involved. It is the hardware implementation of a system.

The dataflow level shows the nature of the flow of data in continuous assignment statements assign keyword. It describes the combinational circuit by their functions rather than their gate structures. For coding in the dataflow style, we only need to know about the logical expression of the circuit.

To start with this, first, you need to declare the module. Now since this the dataflow style, one is supposed to use assign statements. I have used a ternary operator for the output Y. This operator? The hardware schematic for a multiplexer in dataflow level modeling is shown below. You will notice that this schematic is different from that of the gate-level.

It involves the symbol of a multiplexer rather than showing up the logic gates involved, unlike gate-level modeling. This level describes the behavior of a digital system. In most of the cases, we code the behavioral model using the truth table of the circuit.One of these data inputs will be connected to the output based on the values of selection lines.

So, each combination will select only one data input. Multiplexer is also called as Mux. The block diagram of 4x1 Multiplexer is shown in the following figure. One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines. Truth table of 4x1 Multiplexer is shown below. The circuit diagram of 4x1 multiplexer is shown in the following figure. We can easily understand the operation of the above circuit. Similarly, you can implement 8x1 Multiplexer and 16x1 multiplexer by following the same procedure.

Now, let us implement the following two higher-order Multiplexers using lower-order Multiplexers. In this section, let us implement 8x1 Multiplexer using 4x1 Multiplexers and 2x1 Multiplexer. We know that 4x1 Multiplexer has 4 data inputs, 2 selection lines and one output. Whereas, 8x1 Multiplexer has 8 data inputs, 3 selection lines and one output. So, we require two 4x1 Multiplexers in first stage in order to get the 8 data inputs.

Since, each 4x1 Multiplexer produces one output, we require a 2x1 Multiplexer in second stage by considering the outputs of first stage as inputs and to produce the final output.

The Truth table of 8x1 Multiplexer is shown below. We can implement 8x1 Multiplexer using lower order Multiplexers easily by considering the above Truth table.

The block diagram of 8x1 Multiplexer is shown in the following figure. The outputs of first stage 4x1 Multiplexers are applied as inputs of 2x1 Multiplexer that is present in second stage. The other selection line, s 2 is applied to 2x1 Multiplexer. Therefore, the overall combination of two 4x1 Multiplexers and one 2x1 Multiplexer performs as one 8x1 Multiplexer.Table of Contents.

A digital device capable of selecting one input out of its multiple input lines and forwarding it on a common output line is called a multiplexer.

In simple Words, It is the reverse of Demultiplexer Demux. Multiplexer has many inputs and single output. Control signals are used for selecting a data line to be sent as output. Each input line is known as a channel. Multiplexers are essential in communication equipment for placing many signals onto a single channel using Time Division Multiplexing TDM to reduce the number of the channel used per user. Multiplexers can be used for generating any logic function.

Common types of multiplexers are as follow. Details, circuits diagrams, schematic designs, truth tables and application of different kind of MUXES are as follow. When enable is high, MUX is enabled.

The truth table for 2 to 1 MUX is given below. According to the truth table, the expression for output is:. Implantation of Multiplexer using logic gates is given below. The multiplexer is a universal logic function generatorit can implement any logic function. Suppose I want to implement a half adder.

Half adder has 2 output functions; Sum and Carry. For Sum; its truth table:. According to the table given above. According to the table when. This multiplexer has 4 input channels, 1 output,and 2 control signals. Each binary combination of control signal will select one out of four input channels. The truth table for 4 to 1 Multiplexer is given below. According to the truth table, the output Y is:. There are two configuration of making 4 to 1 MUX using 2 to 1 Muxes.

First configuration uses three 2 to 1 Muxes in a specific configuration as shown in the figure given below. The second configuration uses 2 Muxes but it uses the enable pins of Individual Muxes as the 2 nd control signal S 1. Its diagram is given below. In this example, we will implement a full adder as a full adder has 3 input variables. Full adder has 3 inputs; C inA and B. Full adder has 2 output function; Sum and carry out. For Sum; its truth table is:. According to the tablewhen. We will use C inA as control signal S 1S 0 respectively.

For each combination of the control signal, its associated channel is selected and these channels are connected to the input as shown in the figure given below.

And gate using 2:1 mux only

Using the same method for Carry out; the truth table is:. C inA will be used as control signal S 1 ,S 0 respectively.Multiplexing is the property of combining one or more signals and transmitting on a single channel.

This is achieved by the device multiplexer. A multiplexer is the most frequently used combinational circuits and important building block in many in digital systems. These are mostly used to form a selected path between multiple sources and a single destination. A basic multiplexer has various data input lines and a single output line.

These are found in many digital system applications such as data selection and data routing, logic function generators, digital counters with multiplexed displays, telephone network, communication systems, waveform generators, etc.

In this article we are going to discuss about types of multiplexers and its design. The multiplexer or MUX is a digital switch, also called as data selector. It is a combinational circuit with more than one input line, one output line and more than one select line. It allows the binary information from several input lines or sources and depending on the set of select linesparticular input lineis routed onto a single output line.

The basic idea of multiplexing is shown in figure below in which data from several sources are routed to the single output line when the enable switch is ON. The below figure shows the block diagram of a multiplexer consisting of n input lines, m selection lines and one output line. If there are m selection lines, then the number of possible input lines is 2m. For example, if one of the 4 input lines has to be selected, then two select lines are required.

Similarly, to select one of 8 input lines, three select lines are required. Generally the number of data inputs to a multiplexer is a power of two such as 2, 4, 8, 16, etc. Some of the mostly used multiplexers include 2-to-1, 4-to-1, 8-to-1 and to-1 multiplexers.

These multiplexers are available in IC forms with different input and select line configurations. Depends on the select signal, the output is connected to either of the inputs. Since there are two input signals only two ways are possible to connect the inputs to the outputs, so one select is needed to do these operations. If the select line is low, then the output will be switched to D0 input, whereas if select line is high, then the output will be switched to D1 input.

The figure below shows the block diagram of a 2-to-1 multiplexer which connects two 1-bit inputs to a common destination. The truth table of the 2-to-1 multiplexer is shown below.

Depending on the selector switching the inputs are produced at outputsi. From the above output expression, the logic circuit of 2-to-1 multiplexer can be implemented using logic gates as shown in figure.

Thus, the output generated by the OR gate is equal to D0. Therefore, the output of the OR gate is D1. Thus, the above given Boolean expression is satisfied by this circuit.

In some cases, two or more multiplexers are fabricated on a single IC because simple logic gates can implement the multiplexer.When we transfer data, there are a few things that we need to consider to ensure that our transfers are quick, lossless, and efficient.

However, transmitting data requires bandwidth. Or let us put it in even simpler terms. From a layman perspective, if we have a high number of connections or wires between two points, you can transfer a more massive amount of data.

However, transmission lines, connections, even the traces on a circuit board are an expensive commodity — both cost and real estate wise. You ideally need a system where you can transfer the most data using the least connections and cost.

That is one of the core aspects of communication system design. Multiplexing is a concept that is very important in this aspect. Multiplexing means to transmit more than one signal on a single transmission line. In this post, we will look at the multiplexer and demultiplexer circuits. We will also tabulate the multiplexer and demultiplexer truth tables. A multiplexer is a digital combinational logic circuit with n inputs and one output.

Its purpose is to connect one of the inputs to the output line, depending on a control signal. The general symbol of a multiplexer is shown below. Basically, it switches between one of the many input lines and connects them one by one to the output.

It decides which input line to switch to using a control signal. Physically, a multiplexer has n input pins, one output pin, and m control pins.

The mux itself acts like a digitally controlled multi-position switch where the binary code applied to the select inputs controls the data input, which will be switched to the output. To understand the design and working of a multiplexer, we will dive right in.

We will start by designing the simplest of digital multiplexers: the mux. Since we have one control input, there are only two possible values for it. When the control input is 0, the first input line connects to the output. When the control output is 1, the second input line connects to the output. So now you understand how a control line controls which input connects to the output.

As we can see in the multiplexer circuit, depending on the value of the select line Swe can select an input line to connect it to the output.Young Thug) - Camila Cabello.

This week, the USGA have made the decision to revert to a traditional US Open venue after a few years of breaking the mould. In 2013, they returned to the logistically challenging Merion Golf Club (after a 32 year absence) while in 2015, it was the brand-new venue of Chambers Bay.

The total yardage will vary over the four days with a maximum length of 7,900 yards - a daunting number at first glance. Only designed in 2006, the course is a bit of an unknown entity having yet to host a PGA Tour event, though it did stage the 2011 US Amateur.Typically, we believe that outliers represent a random error that we would like to be able to control.

Unfortunately, there is no widely accepted method to remove outliers automatically (however, see the next paragraph), thus what we are left with is to identify any outliers by examining a scatterplot of each important correlation.

How to take notes for content review mcat

Needless to say, outliers may not only artificially increase the value of a correlation coefficient, but they can also decrease the value of a "legitimate" correlation. See also Confidence Ellipse. Quantitative Approach to Outliers. Some researchers use quantitative methods to exclude outliers.

In some areas of research, such "cleaning" of the data is absolutely necessary. For example, in cognitive psychology research on reaction times, even if almost all scores in an experiment are in the range of 300-700 milliseconds, just a few "distracted reactions" of 10-15 seconds will completely change the overall picture.

It should also be noted that in some rare cases, the relative frequency of outliers across a number of groups or cells of a design can be subjected to analysis and provide interpretable results. For example, outliers could be indicative of the occurrence of a phenomenon that is qualitatively different than the typical pattern observed or expected in the sample, thus the relative frequency of outliers could provide evidence of a relative frequency of departure from the process or phenomenon that is typical for the majority of cases in a group.

Correlations in Non-homogeneous Groups. A lack of homogeneity in the sample from which a correlation was calculated can be another factor that biases the value of the correlation. Imagine a case where a correlation coefficient is calculated from data points which came from two different experimental groups but this fact is ignored when the correlation is calculated. Let us assume that the experimental manipulation in one of the groups increased the values of both correlated variables and thus the data from each group form a distinctive "cloud" in the scatterplot (as shown in the graph below).

In such cases, a high correlation may result that is entirely due to the arrangement of the two groups, but which does not represent the "true" relation between the two variables, which may practically be equal to 0 (as could be seen if we looked at each group separately, see the following graph).

If you suspect the influence of such a phenomenon on your correlations and know how to identify such "subsets" of data, try to run the correlations separately in each subset of observations. If you do not know how to identify the hypothetical subsets, try to examine the data with some exploratory multivariate techniques (e. Nonlinear Relations between Variables. Another potential source of problems with the linear (Pearson r) correlation is the shape of the relation.

The possibility of such non-linear relationships is another reason why examining scatterplots is a necessary step in evaluating every correlation.
