Frequency Division Multiplexer & Demultiplexer

Frequency Division Multiplexer/Demultiplexer Trainer Salicon  demonstrates FDM technique.

It basically fulfills the need for communication of two different inputs through a single channel by Frequency Division Multiplexing method. It has the provision for on board modulating signal For reducing the complexity same carriers are used for demodulation also.

In actual FDM communication method carrier is obtained through the modulated output only. 

But the basic concept remains the same. DSB-SC modulation technique is used for modulation and demodulation.
