Question

minimum number of 2 to 1 multiplexers required to build a 16 to 1 multiplexer will be​

Answer 1

Answer:

15

Explanation:

use 8 (2×1) mux that will give you 16 input and 8 output.

use these 8 output as input in 4 (2×1) mux which will give you 4 output. use these 4 output as input in 2 (2×1) mux that will give you two output and finally use 1(2×1) mux to produce 1 output..

so overall you need 8 +4+2+1= 15 mux
