This Unit is designed to enable candidates to gain knowledge and understanding and apply basic digital concepts applicable to combinational logic circuits. It provides candidates with an opportunity to develop the knowledge and skills to be able to design and construct combinational logic circuits to meet a design brief.

On completion of the Unit candidates should be able to:

1. Solve problems involving number systems and binary arithmetic.
2. Draw truth tables for common logic gates and derive combinational logic expressions.
3. Interpret TTL and CMOS data sheets and use these devices in digital systems.
4. Design and implement combinational logic circuits.
