Objective )

Build four circuits by following the figures shown (6.1.1)(6.1.3)(6.1.5)(6.1.8)

Find the functional operation of a combinational logic circuit.

Show common logic using a truth table.

Connect various gates together to create simple logic functions.

Understand the circuits and predicate their outputs.

Put together and test more complicated combinational logic circuits.
