Question

A 32:1 Mux can be designed using:

• A. two 16:1 Muxs and one two-input OR gate
• B. two 16:1 Muxs and one two-input AND gate
• C. two 16:1 Muxs and one two-input NOR gate
• D. two 16:1 Muxs only

Hint:

To design a larger multiplexer, use smaller multiplexers combined with logic gates for selection.

Answer 1

The Correct Option is A

A 32:1 multiplexer can be designed by using two 16:1 multiplexers. The outputs from these multiplexers are combined using an OR gate, which allows for the selection of one of 32 inputs. This is a standard technique used in digital circuit design to build larger multiplexers.
Final Answer: \[ \boxed{\text{(1) two 16:1 Muxs and one two-input OR gate}} \]
