Question

A 4×1 Multiplexer consists of

• A. 2 NAND & 4 NOT gates
• B. 2 NOT & 4 NAND gates
• C. 2 AND & 4 NOT gates
• D. 2 NOT & 4 AND gates

Hint:

Multiplexers use AND gates for input selection and NOT gates for inverting select lines.

Answer 1

The Correct Option is D

A 4:1 multiplexer requires:
- 4 AND gates (to process inputs)
- 2 NOT gates (for selection line complements)
- 1 OR gate (to combine outputs of AND gates)
