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