Q23 | Most demultiplexers facilitate which type of conversion?

decimal-to-hexadecimal
single input, multiple outputs
ac to dc
odd parity to even parity

Answer: single input, multiple outputs

Explaination:
a demultiplexer sends a single input to multiple outputs, depending on the select lines. demultiplexer converts single input into multiple outputs.

Q24 | In 1-to-4 demultiplexer, how many select lines are required?

2
3
4
5

Answer: 2
