Questions & Answers

Q: What are the main features of a demultiplexer?

The main features of a demultiplexer include having one input and multiple outputs, with the number of outputs determined by the select lines. Only one output is activated at a time based on the input conditions.

Q: How can a demultiplexer be designed?

A demultiplexer can be designed by using logic gates. The expression for each output can be designed based on the select lines and the input condition using logic gates.

Q: What is the purpose of select lines in a demultiplexer?

Select lines in a demultiplexer determine the number of outputs. The select lines help activate the corresponding output based on the input condition.

Q: Can a demultiplexer have more than two select lines?

Yes, a demultiplexer can have more than two select lines. The number of select lines determines the number of outputs in a demultiplexer.
