Click on
'Check Connections'
button. If connections are right, click on ‘OK’, then Simulation will become active.
Connect CH1/CH2 of C.R.O. to output terminal of the circuit.
Observe output wave on C.R.O by adjusting C.R.O channel CH1/CH2 and TIME knobs.
Use X Shift and Y Shift buttons for wave shifting.
Measure the time period of output wave at C.R.O. and calculate the frequency by feeding the time period in the given box.
Compare both experimental and theoretical frequencies.
