Frequency Division Multiplexing (FDM) • 2. Time Division Multiplexing (TDM) • 3. Wavelength Division Multiplexing (WDM) • What is Frequency Division Multiplexing • In Frequency Division Multiplexing, the different message signals are modulated at the different carrier frequencies. In this way, the modulated signals are separate from each other in the frequency domain. • The modulated signals are combined together to form the composite signal and this signal is sent over the shared medium or channel. • Applications of Frequency Division Multiplexing Technique: • 1) AM and FM radio Broadcast • 2) Cable TV • 3) Satellite Communication • 4) Telemetry • 5) Telephony Systems • 6) Early Generation Cellular Networks • The link for the other useful videos related to communication: • 1) What is Modulation? • • What is Modulation ?
