How would you implement a function using multiplexers?

Implementation of SOP function using multiplexer

1. Step 1: Draw the truth table for the given number of variable function.
2. Step 2: Consider one variable as input and remaining variables as select lines.
3. Step 3: Form a matrix where input lines of MUX are columns and input variable and its compliment are rows.

What are three uses examples of multiplexers?

Multiplexers are used in various applications wherein multiple-data need to be transmitted by using a single line.

• Communication System.
• Computer Memory.
• Telephone Network.
• Transmission from the Computer System of a Satellite.
• Communication System.
• Arithmetic Logic Unit.
• Serial to Parallel Converter.

How multiplexers are used in circuit design?

Multiplexers, or MUX’s, can be either digital circuits made from high speed logic gates used to switch digital or binary data or they can be analogue types using transistors, MOSFET’s or relays to switch one of the voltage or current inputs through to a single output.

What is multiplexer explain with the help of example?

A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal. Multiplexers can also be used to implement Boolean functions of multiple variables.

How do you implement an 8 to 1 multiplexer?

All you need to do is connect the eight inputs to GND (Ground) or VDD to match the 0s and 1s of the Q output of the truth table. What this tells us is that the CD4512 is an 8:1 multiplexer. The three selection inputs, A, B, and C are used to select one of the eight D0 to D7 data inputs.

What is multiplexer circuit?

Multiplexer is a combinational circuit that has maximum of 2n data inputs, ‘n’ selection lines and single output line. 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.

What are the benefits of multiplexers?

The advantage of multiplexing is that we can transmit a large number of signals to a single medium. This channel can be a physical medium like a coaxial, metallic conductor or a wireless link and will have to handle multiple signals at a time. Thus the cost of transmission can be reduced.

How many types of multiplexers are there?

There are mainly two types of multiplexers, namely analog and digital. They are further divided into Frequency Division Multiplexing (FDM), Wavelength Division Multiplexing (WDM), and Time Division Multiplexing (TDM).

What is multiplexer implement 8 is to 1 multiplexer using basic gates?

An 8-to-1 multiplexer consists of eight data inputs D0 through D7, three input select lines S0 through S2 and a single output line Y. Depending on the select lines combinations, multiplexer selects the inputs.

How would you implement a 4 variable function using 8 1 mux?

The given function is in terms of minterms and is to be implemented using a 8:1 MUX. An 8:1 MUX has three select lines, whereas the given function is a 4 variable function. Hence a logic is needed to give combination of A as inputs while only B, C and D as select line inputs. The method for the same is described below.

What is a digital multiplexer circuit?

Digital Circuits – Multiplexers. Multiplexer is a combinational circuit that has maximum of 2 n data inputs, ‘n’ selection lines and single output line. One of these data inputs will be connected to the output based on the values of selection lines.

How many inputs and outputs does 4×1 multiplexer have?

4×1 Multiplexer has four data inputs I 3, I 2, I 1 & I 0, two selection lines s 1 & s 0 and one output Y. The block diagram of 4×1 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.

What are control lines in a multiplexer?

Generally, the selection of each input line in a multiplexer is controlled by an additional set of inputs called control lines and according to the binary condition of these control inputs, either “HIGH” or “LOW” the appropriate data input is connected directly to the output.

What are the different types of multiplexer?
