What is a multiplexer explain with an example?

A multiplexer is a circuit used to select and route any one of the several input signals to a single output. A simple example of an non-electronic circuit of a multiplexer is a single pole multi-position switch. For analog application, multiplexer are built using relays and transistor switches.

What are the types of digital multiplexer?

There are several different types of multiplexers, in this article we talk about the following:

• Time Division Multiplexer.
• Statistical Multiplexer.
• Inverse Multiplexer.
• Space Division Multiplexer.
• Frequency Division Multiplexer.
• Wavelength Division Multiplexer.

How does a multiplexer digital logic work?

How Does a Multiplexer Work? The multiplexer works like a multiple-input and single-output switch. The output gets connected to only one of the n data inputs at a given instant of time. Therefore, the multiplexer is ‘many into one’ and it works as the digital equivalent of an analog selector switch.

What do multiplexers do?

A multiplexer (MUX) is a device that can receive multiple input signals and synthesize a single output signal in a recoverable manner for each input signal. It is also an integrated system that usually contains a certain number of data inputs and a single output.

What is a 4 1 multiplexer?

A 4-to-1 multiplexer consists four data input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y. The select lines S0 and S1 select one of the four input lines to connect the output line.

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 in data communication?

Multiplexing is the technology that is able to combine multiple communication signals together in order for them to traverse an otherwise single signal communication medium simultaneously. Multiplexing is widely used in telephony, data communications, and audio/video broadcasting.

What is a 4-to-1 multiplexer?

What is multiplexer explain its working and truth table?

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. Since there are ‘n’ selection lines, there will be 2n possible combinations of zeros and ones.

What is meant by multiplexer explain with diagram and truth table the operation of 4 to 1 line multiplexer?

The truth table of a 4-to-1 multiplexer is shown below in which four input combinations 00, 10, 01 and 11 on the select lines respectively switches the inputs D0, D2, D1 and D3 to the output. That means when S0=0 and S1 =0, the output at Y is D0, similarly Y is D1 if the select inputs S0=0 and S1= 1 and so on.

What is latch in digital logic design?

A latch is a storage device that holds the data using the feedback lane. The latch stores 1 -bit until the device set to 1. The latch changes the stored data and constantly trials the inputs when the enable input set to 1. Based on the enable signal, the circuit works in two states.

What is a digital multiplexer?

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. Since there are ‘n’ selection lines, there will be 2 n possible combinations of zeros and ones.

How many data inputs and outputs does a multiplexer have?

Depending on the digital code applied at the select inputs, one of the n data inputs is selected and transmitted to the single output. Hence, a multiplexer has maximum 2 n data input lines, ‘m’ selects lines, and one output line. The block diagram of an n-to-1 multiplexer and its equivalent circuit is shown in the figure below.

How does a single 8-channel multiplexer work?

For example, a single 8-channel 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 is a 2 to 1 multiplexer circuit?

2 to 1 Multiplexer Circuit A 2-to-1 multiplexer is the digital multiplexer circuit that has two data inputs D 0 and D 1, one selects line S and one output Y. To implement a 2-to-1 multiplexer circuit we need 2 AND gates, an OR gate, and a NOT gate.
