What is multiplexer circuit diagram?
The multiplexer is a combinational logic circuit designed to switch one of several input lines to a single common output line.
What is multiplexer explain with block diagram and circuit diagram?
A multiplexer is a combinational circuit that has 2n input lines and a single output line. Simply, the multiplexer is a multi-input and single-output combinational circuit. The binary information is received from the input lines and directed to the output line.
What is meant by multiplexer explain with diagram and truth table the operation of 4 to 1 line 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 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.
How does multiplexer circuit work?
A multiplexer is a system of multiple inputs and just one output to receive signals coming from multiple acquisition networks. The device transfers all input signals to a microprocessor, which receives and processes the data, transmits it to the output devices, and controls the system as a whole.
What is multiplexer with example?
Multiplexer means many into one. 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. A mechanical switch cannot perform this task efficiently. …
What is multiplexer explain?
In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines.
What is multiplexer explain with one suitable 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.

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 the function of a multiplexer?
The basic function of a multiplexer: combining multiple inputs into a single data stream. On the receiving side, a demultiplexer splits the single data stream into the original multiple signals.
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.
What’s the difference between a multiplexer and a decoder?
Multiplexer is a device which consists of multiple input channels thru single line while decoders consist of multiple inputs passing thru multiple output. Multiplexer converts inputs from unary codes (initial) to binary codes while decoder converts binary codes to inputs.
How is a multiplexer a combinational circuit?
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 is the output of a multiplexer controlled?
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.
How many gates are in a multiplexer logic diagram?
As you can see clearly a multiplexer logic diagram simply consists of 2 Not Gates, 4 AND Gates, and 1 OR Gate. The outputs of all the AND gates are added using a single OR Gate. *Please Note: These are affiliate links.
How are the first two MUX connected in a multiplexer?
To achieve the first two MUX is connected in parallel and then the output of those two are feeded as input to the 3 rd MUX as shown below. The control/select line of the first two MUX is connected together to form a single line (S 0) and then the control line of the 3 rd MUX is used as the second control/select signal.
