IT-4104 Frequency Division Multiplexing Transceiver Trainer

Experiments Included:

  • Study of DSBSC modulation / demodulation.
  • Study of the Frequency Division Multiplexing / De-multiplexing with sinusoidal wave.

Description

FDM trainer explores concepts relating to Frequency Division Multiplexing and De-multiplexing. This trainer is self contained with two Audio inputs through audio generators and two DSB Modulator and De-modulators.

Both carriers are generated using crystal oscillator. This ensure stable carrier. At De-modulator section,  Ceramic Band Pass Filter, DSB De-modulator and Low Pass Filter is used.
