Apparatus Required :-
1. IC’s – 7400(NAND Gate), 7402(NOR Gate)
2. Electronic Circuit Designer
3. Connecting patch chords
Universale Gate :-
NOR gate is said to be a universal gate because any digital system can be imple mented with it. To show that any Boolean function can be implement with NAND OR NOR gates, we need only show that the logic operations AND, OR , NOT , X-OR, and X-NOR gates can be implemented with NAND and NOR gates. A conve- nient way to implement a combinational circuit with NAND and NOR gates is to obtain the simplifie Boolean functions in terms of AND, OR , NOT, X-OR ,and X-NOR gates and convert the functions to NAND or NOR logic.
Procedure :-
1. Connect the logic gates as shown in the diagrams.
2. Feed the logic signals 0 or 1 from the logic input switches in different combinations at the inputs A & B.
3. Monitor the output using logic output LED indicators.
4. Repeat steps 1 to 3 for X-OR operations and compare the outputs with the truth tables.
