Use of multiplexer

A Multiplexer is used to increase the efficiency of the communication system by allowing the transmission of data such as audio & video data from different channels via cables and single lines.

What is multiplexer and its uses?

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.

Why do we use multiplexing?

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.

What is the role of multiplexer and decoder?

Multiplexer is a device which consists of multiple input channels thru single line while decoders consist of multiple inputs passing thru multiple output. 3. Multiplexer converts inputs from unary codes (initial) to binary codes while decoder converts binary codes to inputs.

Is multiplexer a decoder or encoder?

An encoder with enable pins is called multiplexer while a decoder with enable pins is called demultiplexer.

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.

What is multiplexer and types?

There are mainly two types of multiplexers, namely analog and digital. They are further divided into FDM, WDM, and TDM.

What is the role of multiplexer when enable input is high?

Explanation: If enable input is high then the multiplexer is disabled because enable input is in inverted mode always (i.e. E').

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. ... Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems.

Why a multiplexer is called a data selector?

Basic Multiplexing Switch

In digital electronics, multiplexers are also known as data selectors because they can “select” each input line, are constructed from individual Analogue Switches encased in a single IC package as opposed to the “mechanical” type selectors such as normal conventional switches and relays.

Can a multiplexer work as a encoder?

10. Can an encoder be called a multiplexer? Explanation: A multiplexer or MUX is a combination circuit that contains more than one input line, one output line and more than one selection line. Whereas, an encoder is also considered a type of multiplexer but without a single output line and without any selection lines.

How a multiplexer is converted to decoder?

Multiplexer converts inputs from unary codes (initial) to binary codes while decoder converts binary codes to inputs. The circuit is designed with AND and NAND logic gates. It takes 3 binary inputs and activates one of the eight outputs. 3 to 8 line decoder circuit is also called as binary to an octal decoder.

What is enable in multiplexer?

An enable input makes the multiplexer operate. When EN = 0, the output is High-Z or less commonly LOW (depending on the specific device). When EN = 1, the multiplexer performs its operation depending on the selection line.

What is the importance of the use of the selection bit and the data bits?

Selection bits determine which value will be chosen in mux or demux. Data bits are the inputs to the mux.

What is multiplexer 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.
