Question

Which is the major functioning responsibility of the multiplexing combinational circuit?

(a) Decoding the binary information

(b) Generation of all minterms in an output function with OR-gate

(c) Generation of selected path between multiple sources and a single destination

(d) Encoding of binary information

I got this question in examination.

Enquiry is from Multiplexers (Data Selectors) topic in division Combinational Circuits of Digital Circuits

Answer 1

The correct choice is (c) Generation of selected path between multiple sources and a single destination

The best explanation: The major functioning responsibility of the multiplexing combinational circuit is generation of selected path between multiple sources and a single destination because it makes the circuit too flexible. 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.
