Frequency-Division Multiplexing (FDM)
is a scheme in which numerous signals are combined for transmission on a
single communications line or channel. It is analog technique. Each signal is
assigned a different frequency (sub channel) within the main chann
Concepts and demultiplexing
The signal generated by each sending device
modulate a different carrier frequency.
The modulated signals are combined to a single
composite signal that can be transported by

What is MODULATION?
It is the process of altering a characteristic of the carrier in accordance
with the instantaneous value of the intelligence signal.
