Electronics Communication/Signal Processing/Signal Modulation & Demodulation

Signal Modulation & Demodulation
Signal modulation is the process of mixing signal wave of low frequency with a carrier wave of high frequency to produce a broadcast wave for transmission over a long distance from a transmitter to a receiver.

Signal Modulation
Signal modulation takes place at the transmitter
 * 1) /AM Modulation/
 * 2) /FM Modulation/
 * 3) /PM Modulation/

Signal Demodulation
Signal modulation takes place at the receiver. The process involves tuning, rectifying and converting the modulation wave into a signal wave


 * 1) /AM Demodulation/
 * 2) /FM Demodulation/
 * 3) /PM Demodulation/
