Aim:-
To design and construct of 3-bit Asynchronous up and down counters,2-bit up/down
counter.
Apparatus:
1. IC’s - 7408,7476,7400,7432
2. Electronic circuit designer
3. Connecting patch chords
Procedure:
1. Connections are made as per the circuit diagram
2. Switch on the power supply.
3. Apply clock pulses and note the outputs after each clock pulse and note done the out puts.
Precautions:
1. All the connections should be made properly.
2. IC should not be reversed.
Result:
3-bit Asynchronous up and down counters,2-bit up/down counter are designed and
truth tables are verified.
