Logic Gates - Technical MCQs

Q1:

The output of an AND gate with three inputs, A, B, and C, is HIGH when ________.

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

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

C A = 1, B = 1, C = 1

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

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

The output of an AND gate is high (1) only when all the inputs are high, even if anyone of the input is low (0) then the output will be low (0).
