1.	State The Techniques Of Demodulation?
Answer» There are several ways of demodulation depending on how parameters of the carrier signal, such as amplitude, frequency or phase. For a signal MODULATED with a linear MODULATION, LIKE AM, we can USE a SYNCHRONOUS detector. For a signal modulated with an angular modulation, we must use an FM demodulator or a PM demodulator. There are several ways of demodulation depending on how parameters of the carrier signal, such as amplitude, frequency or phase.
