PROCEDURE: 1. Connect the circuit as shown in the circuit diagram. 2. Usually a + Ve supply voltage of about 10 V is applied as source voltage to V. 3. In the normal operation transistor Q, is ON and output voltage across the base and collector are noted. 4. Then an external triggering is applied from the high-pass filter circuit. 5. Then the transistor Q, is OFF state, and then the voltage across the junction of the transistor Q is noted 6. The output waveforms are plotted for Ven , VH1 , Ve2: Vin which are observed from the CRO. RESULT: A monostable multivibrator is studied and output wave forms were verified
