What do you mean by multiplexer and demultiplexer?

Multiplexer processes the digital information from various sources into a single source. Demultiplexer receives digital information from a single source and converts it into several sources. It is known as Data Selector. It is known as Data Distributor. Multiplexer is a digital switch.

What is mux implementation?

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.

How multiplexer is implemented in a circuit?

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 is a multiplexer in networking?

A multiplexer is a device that takes multiple analog signals and forwards the selected input into a single line. These devices are used to increase the amount of data that can be transmitted over a network. Like other types of network equipment, network multiplexers support specific network protocols like Ethernet.

What is the function implemented by following multiplexer?

The multiplexer, shortened to “MUX” or “MPX”, is a combinational logic circuit designed to switch one of several input lines through to a single common output line by the application of a control signal.

What is encoder and decoder multiplexer and demultiplexer?

The digital circuits that perform encoding of digital information are called encoders while digital circuits that decode the coded digital information are called decoders. An encoder with enable pins is called multiplexer while a decoder with enable pins is called demultiplexer.

What are the uses of demultiplexer?

Demultiplexer (Demux) and Multiplexer (MUX) both are used in communication systems to carry multiple data signals (i.e. In Arithmetic logic unit (ALU), the output of ALU can be stored in storage unit (multiple registers) by using Demultiplexer. Demultiplexer is also used in serial to parallel converter.

How can a decoder be used as a demultiplexer?

Demultiplexers The number of data outputs is equal to 2 N where N is the number of control select leads. The 74139 is a 1-of-4 decoder that can also be used as a demultiplexer. To use the 74139 as a demultiplexer, connect the incoming data to the enable input and use the A0 and A1 inputs as the control select lines.

Why is multiplexer called Data Selector?

Multiplexers are mainly used to increase the amount of data that can be sent over the network within a certain amount of time and bandwidth. A multiplexer is also called a data selector. Multiplexers can also be used to implement Boolean functions of multiple variables.

What is a multiplexer and how does it work?

Multiplexer. In electronics, a multiplexer (or mux) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. A multiplexer of inputs has select lines, which are used to select which input line to send to the output.
