In Pulse Amplitude Modulation (PAM) technique, the amplitude of the pulse carrier varies, which is proportional to the instantaneous amplitude of the message signal.The pulse amplitude modulated signal will follow the amplitude of the original signal, as the signal traces out the path of the ...
Power Electronics - Pulse Width Modulation - PWM is a technique that is used to reduce the overall harmonic distortion (THD) in a load current. It uses a pulse wave in rectangular/square form that results in a variable average waveform value f(t), after
Asampling signalis a periodic train of pulses, havingunit amplitude, sampled at equal intervals of timeTs, which is called as theSampling time. This data is transmitted at the time instantsTsand the carrier signal is transmitted at the remaining time. ...
