Question

The value of \(Q\) in the given digital circuit is

• A. \[ Q=A+B+B.C(B+C) \]
• B. \[ Q=A.B+B.C(B+C) \]
• C. \[ Q=A+B+B.C(B.C) \]
• D. \[ Q=A.B+\overline{B}\,\overline{C}(B+C) \]

Hint:

Useful Boolean identities: \[ A+A.B=A, \] \[ A(A+B)=A, \] \[ (A+B)C=AC+BC. \] Always evaluate a digital circuit gate-by-gate from inputs to output.

Answer 1

The Correct Option is B
