What does a multiplexor do?

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.

What is multiplexer in simple words?

A multiplexer (MUX) is a device allowing one or more low-speed analog or digital input signals to be selected, combined and transmitted at a higher speed on a single shared medium or within a single shared device. ... A MUX functions as a multiple-input, single-output switch.

What is a multiplexor gate?

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 with 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. Multi-position switches are widely used in many electronics circuits.

What is a multiplexer tree?

What is multiplexer tree? ... A number of m-to-1 multiplexers can be arranged in a tree topology to obtain a bigger n-to-1 multiplexer is called Multiplexer Tree where n>m. Bigger Multiplexer can be obtained by combining smaller Multiplexers.

Is multiplexer a decoder or encoder?

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 is 4x1 multiplexer?

4x1 Multiplexer has four data inputs I₃, I₂, I₁ & I₀, two selection lines s₁ & s₀ and one output Y. ... 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.

What does a decoder do?

A decoder is a device that generates the original signal as output from the coded input signal and converts n lines of input into 2n lines of output. An AND gate can be used as the basic decoding element because it produces a high output only when all inputs are high.

What is the difference between a multiplexor and a demultiplexer?

A multiplexer is a combinational circuit that provides single output but accepts multiple data inputs. A demultiplexer is a combinational circuit that takes single input but that input can be directed through multiple outputs.

What are the basic requirements of a multiplexer?

The basic function of a multiplexer: combining multiple inputs into a single data stream. ... A 2-to-1 mux. A 4:1 MUX circuit using 3 input AND and other gates.

Which of the following is correct for multiplexer?

Which of the following is correct for multiplexer? Explanation: Multiplexer has several inputs and a single output line and it is used for data selection. Explanation: Multiplexers work with both analog and digital signals. Explanation: TDM or Time division multiplexing is a type of multiplexing.

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 latch circuit?

In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs.

What is basic difference between encoder and multiplexer?

The encoder is a combinational circuit element that encodes a set of binary codes into another set of binary codes containing a smaller number of bits. The multiplexer is a combinational circuit element that channels one of its many inputs to its only output depending on the selection inputs.

What is digital encoder?

An encoder (or "simple encoder") in digital electronics is a one-hot to binary converter. That is, if there are 2ⁿ input lines, and at most only one of them will ever be high, the binary code of this 'hot' line is produced on the n-bit output lines. A binary encoder is the dual of a binary decoder.
