Combinational Logic Analysis - Technical MCQs

Q1:

A 4-variable AND-OR circuit produces a 1 at its Y output. Which combination of inputs is correct?

A A = 0, B = 0, C = 0, D = 0

B A = 0, B = 1, C = 1, D = 0

C A = 1, B = 1, C = 0, D = 0

D A = 1, B = 0, C = 0, D = 0

ANS:C - A = 1, B = 1, C = 0, D = 0

Put all combination into two AND gates with One OR gate. In one combition you will get 1 as output. You will get option C as answer.
