Pulse Amplitude Modulation (PAM) is based on a conversion the signal into a series of amplitude-modulated pulses. The bandwidth requirements are given by To generate amplitude modulated wave and determine the percentage modulation. 2. Aim: To generate the pulse width modulated and demodulated signals. Pulse amplitude modulation and demodulation. 11. Pulse width modulation and demodulation. 12. Pulse Position modulation and demodulation. 13. Frequency 7. To study sensitivity, selectivity, and fidelity characteristics of super heterodyne receiver. 8. To study Pulse Width Modulation and Pulse Position Modulation. 9. EXPERIMENTAL SECTION. LIST OF EXPERIMENTS. Experiment 1: To Study the PWM Modulation and Demodulation (64 KHz Carrier) Experiment Name: Generation of PAM. Theory: Pulse amplitude modulation is a scheme, which alters the amplitude of regularly spaced rectangular pulses inDec 4, 2017 - Nov 14, 2014 - COMMUNICATIONS LAB.
