Question

One multiplexer can take the place of ____________

(a) Several SSI logic gates

(b) Combinational logic circuits

(c) Several Ex-NOR gates

(d) Several SSI logic gates or combinational logic circuits

I had been asked this question in examination.

The question is from Multiplexers (Data Selectors) topic in section Combinational Circuits of Digital Circuits

Answer 1

Correct answer is (d) Several SSI logic gates or combinational logic circuits

The explanation is: A combinational circuit that selects one from many inputs is known as Multiplexer. One multiplexer can take the place of several SSI logic gates or combinational logic circuits because it has a lot of functions to perform different operations.
