Answer 1

The answer to the question, "How many outputs would two 8-line to 3-line encoders, expanded to a 16-line to 4-line encoder have?", will be 4.

An encoder does the task opposite to a multiplexer. It takes multiple inputs and transfers them through a lesser number of output sources.

There are various kinds of encoders too.
