Syllabus
1. Study and design of AM modulator and demodulator. (Full AM, SSB, DSBSC, SSBSC)
2. Using MATLAB generate a carrier and a modulating signal. Modulate the carrier using AM. Show the modulated waveform in time domain and analyze its frequency spectrum. Repeat the simulation for modulating signal being square, triangular and other forms of waveform.
3. Study of FM modulation and Demodulation Techniques.
4. Using MATLAB generate a carrier and a modulating signal. Modulate the carrier using FM. Show the waveform in time domain and analyze its frequency spectrum. Repeat the simulation for modulating signal being square, triangular and other forms of waveform.
5. Using Lab-View software simulate AM modulation and demodulation system.
6. Using Lab-View software simulate FM modulation and demodulation system.
7. Design a receiver to demodulate and receive the signal from an AM radio station.
8. Design a receiver to demodulate and receive the signal from the local FM radio station.
