40501 - Amplitude Modulation and Demodulation 6/6 Slowly increase the level of audio signal input and keep observing the amplitude 3. modulated waveform on C.R.O For a particular level of Audio signal measure A and B as shown in fig. 1(d) 4. Calculate percentage modulation A-B X100 m A +B FIG 1 (D) AM. SIGNALS AS A RESULT OF DIFFERENT LEVELS OF AUDIO SIGNAL OBJECT 4:- TO DEMODULATE AMPLITUDE MODULATED WAVEFORM AND OBSERVE ON C.R.O. PROCEDURE Switch ON the power supply Connect carrier wave to the sockets marked CARRIER IN and 1 KHz audio signal from Audio Frequency Generator to the sockets marked AUDIO IN. 1. Connect the sockets marked modulated output to the sockets marked Modulated Signal IN of the demodulating circuit. 3. Observe the waveform at sockets marked DEMODULATED OUTPUT. The waveform should be a 1 KHz Audio Signal as fed from the Audio Frequency Generator. 4. REFERENCES 1.
