Combinational Logic Circuits - Technical MCQs

Q1:

A multiplexed display:

A accepts data inputs from one line and passes this data to multiple output lines

B uses one display to present two or more pieces of information

C accepts data inputs from multiple lines and passes this data to multiple output lines

D accepts data inputs from several lines and multiplexes this input data to four BCD lines

ANS:B - uses one display to present two or more pieces of information

More pieces of information means more than 1 i/p & 1display means 1 O/p. MUX is multi i/p single O/p circuit.
