Question

1 : 32 demultiplexer can be designed with how much select lines?​

Answer 1

There are two select lines

Number of select lines in 1:32 Demux is

 5 select lines will be required for 32 inputs, as (2^5) = 32

Explanation:

A demultiplexer sends a single input to multiple outputs. The select lines depends on the size of the demultiplexer.

The process of getting information from one input and transmitting the same over one of many outputs is called Demultiplexing and Demultiplexing is just the opposite of multiplexing.

It is a combinational logic circuit that receives the information on a single input line and transmits the same information over one of ‘n’ possible output lines.
