A digital multiplexer is a combinational circuit that selects ________...
Introduction:
A digital multiplexer is a combinational circuit that is used to select one digital information from multiple sources and transmit the selected one. It is commonly known as a data selector or data multiplexer. The selection of the input data is based on the control signals provided to the circuit.
Explanation:
A digital multiplexer has multiple input lines, one output line, and several control signals. The number of input lines in a multiplexer depends on the number of sources from which the digital information is received. The control signals determine which input line is selected and transmitted to the output line.
Working:
The operation of a digital multiplexer can be understood with the help of its truth table. Let's consider a 4:1 multiplexer with 4 input lines (D0, D1, D2, D3), 1 output line (Y), and 2 control signals (S0, S1).
- The control signals (S0, S1) determine which input line is selected and transmitted to the output line.
- For example, if (S0, S1) = (0, 0), the input line D0 is selected and transmitted to the output line.
- Similarly, for (S0, S1) = (0, 1), D1 is selected; for (S0, S1) = (1, 0), D2 is selected; and for (S0, S1) = (1, 1), D3 is selected.
- The selected input is then transmitted to the output line Y.
Benefits:
A digital multiplexer offers several benefits in digital circuit design:
- It reduces the complexity of circuitry by enabling the selection of one digital information from multiple sources using a single circuit.
- It saves space on integrated circuits by eliminating the need for separate circuits for each input source.
- It reduces the number of interconnections required in a circuit, leading to improved reliability and reduced power consumption.
Conclusion:
In conclusion, a digital multiplexer is a combinational circuit that selects one digital information from several sources and transmits the selected one. It is an essential component in digital circuit design, providing flexibility, simplicity, and efficiency in data selection and transmission.
