MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -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.

Detailed explanation-2: -Explanation: A multiplexer (or MUX) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line, depending on the active select lines. Since many operational behaviour can be performed by using a multiplexer.

Detailed explanation-3: -Multiplexer is a combinational circuit that has maximum of 2n 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 2n possible combinations of zeros and ones.

Detailed explanation-4: -Which of the following is not a multiplexer? Explanation: Multiplexer is a multiple input single output system. 9. Demultiplexer act as an encoder.
