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 /AM Modulation/ /FM Modulation/ /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 /AM Demodulation/ /FM Demodulation/ /PM Demodulation/
