transmission medium. Different carries frequencies are assigned to different users. We can use any modulation scheme to assign carrier frequency. Example: FDM can also be used to combine signals before final modulation onto a carrier wave. In this case the carrier signals are referred to as subcarriers: an example is stereo FM transmission‚ where a 38 kHz subcarrier is used to separate the left-right difference signal from the central left-right sum channel‚ prior to the frequency modulation of the
