Show hintHide hint
Think of it as a way to sort or direct data.
Question 2.
How many select lines are needed for a demultiplexer with 4 outputs?
Show hintHide hint
Remember the formula involves logarithm.
3Question 3.
What is the function of a demultiplexer?

Show hintHide hint
Consider how each select line controls the output.
Question 6.
Given an ALU with two inputs and four operations selected via 2 bits, outline a truth table for its operations.
