MCQ
To get an output Y=1 from the circuit above, the input must be:
  • A
    A-0 B-1 C-0
  • B
    A-1 B-0 C-0
  • C
    A-1 B-0 C-1
  • D
    A-1 B-1 C-0
✓

Answer

  1. A-1 B-0 C-1

Explanation:

Logic gate OR is used for addition of the input signals and Logic gate AND is used for multiplication of the input signals. Hence, here inputs A = 1, B = 0 and C = 1 will yield the output Y = 1.
