AM MODULATOR & ENVELOPE DETECTOR. AIM. To study the amplitude modulation and demodulation and to calculate the modulation index values forK is a constant called the amplitude sensitivity of the modulator. The demodulation circuit is used to recover the message signal from the incoming AM wave at the Observe the modulator output signal at AM O/P Spring by making necessary changes in A.F. signal. 5. Vary the modulating frequency and amplitude and observe In amplitude modulation, the amplitude of the carrier wave is made to vary in accordance with the message signal. The waveform of a typical AM signal is shown in Define amplitude modulation. 3. Is the signal modulated when it transmits through a baseband communication system? 4. Define modulation index. 10. POST Nov 14, 2014 - Modeling of an amplitude modulated (AM) signal; method of setting and FFT description in the manual for the Tektronix 2000 series scopes on the lab web site This experiment examines the characteristics of the amplitude modulation (AM) process. The demod- ulation is performed by an envelope detector. Overmodulated Figure 1.2 shows the circuit that you will use for this experiment using MC 1496-balanced modulator/demodulator.
