OBJECTIVtrS
After you have completed this fesson you^ will be able to:
- Wire and tesl- a COMBINATION LOGIC^ circuit.
- Wrlte the function of equivalent circuit
- Write the Boolean Expression and simplify it using appropriate Boolean Theorem
CONCEPTS
. COMBINATION LOGIC GATtrS
In previous^ experiments^ you have^ learned^ that^ Logic^ Gates can^ be^ used^ to evaluaLe when all inputs are at logicat 1 (AND^ Gate), when^ ANY^ input is^ at logicat 1 (oR^ Gate) and that an input can be reversed^ between^ logical^1 and O (INVERTER Gate). When two or more logic gates^ are used in combination to evafuate various input conditions, the resulting^ circuit is called COMBINATION LOGIC.

- Construct the foll-ow-ing^ circuits^ (figures Lf to^ L2)^ on^ the logic trainer. Operate the circuit and fill^ in the^ accompanylng^ truth^ tables. Compares the truth tables for^ each^ of the circuits^ then^ determine^ the Boofean expressions for both circuits and^ fill^ out the equality^ statement (BooIean rule).
