Boolean Algebra and Logic Simplification - Technical MCQs

Q1:

Determine the values of A, B, C, and D that make the product term equal to 1.

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

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

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

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

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

Abar and Cbar both has "NOT" gate, if we include '0', we can get '1', therefor 1*1*1*1 = 1. A is the answer.
