PROCEDURE: 1. Connect the circuit as shown in the circuit diagram. 2. An external triggering signal across the cathode terminal of the diode was applied. 3. The output voltage Vca across the collector Q, considering that Q is off and Q is on was taken. 4. The output voltage Viz across the base of transistor Q, was collected. 5. The above steps were repeated for Q, is on and Q, is off. 6. The output waveforms from the CRO was noted down and the graph was plotted RESULT: A Bistable multivibrator is studied and output wave forms are verified
