Combinational Logic Circuits - Technical MCQs

Q1:

A basic multiplexer principle can be demonstrated through the use of a:

A single-pole relay

B DPDT switch

C rotary switch

D linear stepper

ANS:C - rotary switch

Rotary switch is used to select an exclusive circuit connection among several by merely turning a rotary knob to a discrete position. It is also known as selector switch. Basic principle of multiplexer is data selecting.
