What is PWM?
If the duration of pulse or pulse width is changed as per the samples of message signal the resulting modulation is known as PWM (Pulse width modulation).
A demodulator is an electronic circuit that is used to recover the information content from the modulated carrier wave.The signal output from a demodulator may represent sound, images or binary data.
1 thought on “Demodulation of PWM”
Sir i have two questions rising in my mind:
1) If the clipper being used here gets faulty and it starts to clip voltage levels within the rising ramp function/s. Can you suggest any modification or any alteration in the above mentioned block diagram that could make you get rid of the fault.
2) let suppose if synchronous pulse generator will generate a pulse waveform such that the pulse will end at the ending of each PWM pulse. How this slight variation in the operation of the system would hamper or shall not hamper the final output of the system
