A digital multiplexer is a combinational circuit that selects ________...
Digital Multiplexer:
A digital multiplexer is a combinational circuit that selects one digital information from several sources and transmits the selected one. It has several input lines, one output line, and a select line. The select line determines which input line is transmitted to the output line.
Working of Digital Multiplexer:
The working of the digital multiplexer can be explained as follows:
- The digital multiplexer has several input lines and one output line. The input lines are labelled as I0, I1, I2, … In-1 and the output line is labelled as Y.
- The digital multiplexer also has a select line labelled as S.
- The number of input lines is defined by the number of select lines, which is given by 2n, where n is the number of select lines.
- Depending on the value of the select line, the corresponding input line is transmitted to the output line.
- The output line can be represented as Y = S.I0 + S'.I1, where S' is the complement of S.
- The truth table of the digital multiplexer is given below:
S | I0 | I1 | I2 | I3 | Y
--|----|----|----|----|--
0 | 0 | 0 | 0 | 0 | 0
0 | 1 | 0 | 0 | 0 | 1
0 | 0 | 1 | 0 | 0 | 1

1 | 1 | 1 | 0 | 1 | 1
1 | 1 | 0 | 1 | 1 | 1
1 | 1 | 1 | 1 | 1 | 1
Uses of Digital Multiplexer:
The digital multiplexer is used in various applications such as:
- Digital communication systems
- Digital signal processing
- Computer memory systems
- Microprocessors and microcontrollers
- Digital audio and video systems
Conclusion:
Thus, a digital multiplexer is a combinational circuit that selects one digital information from several sources and transmits the selected one. It has several input lines, one output line, and a select line. The select line determines which input line is transmitted to the output line. The digital multiplexer is used
