Frequency Modulation and Demodulation Trainer

  • FM Transmitter and Receiver Trainer has been designed with a view to provide practical and experimental knowledge of Frequency Modulation & Demodulation Trainer technique as practically implemented in Analog Communication system on a SINGLE P.C.B. of size 300 x 400 mm.


To Study Theory of Frequency Modulation & Demodulation:

  • Frequency Modulation via varactor / reactance Modulation
  • Frequency Demodulation via Detuned Resonant/Ratio/Quadrature/Foster - Seeley/Phase locked loop detector
  • Separate VCO circuit to demonstrate FM waveform


The board consists of the following built-in parts:


  • ± 12DC IC Regulated power supply

FM Modulating signal generator:

  • Sine wave

Frequency Range:

  • 300 Hz to 3.4 Khz

Amplitude Range:

  • 0 to 5 Vpp.

Modulator Type:

Varactor modulator (With carrier frequency adjustment):

  • Reactance Modulator (With carrier frequency adjustment)

Demodulator (Detuned resonant detector): 

  • Quadrature detector
  • Foster - Seeley Detector
  • Ratio Detector
  • Phase locked loop Detector


  • 1 No. (With gain adjustment) Allows FM input signal to be amplitude modulated by a noise input to demodulation.

Low pass Filter:

  • 3.4 KHz. Cut of frequency Amplifier (with adjustable gain)

VCO Circuit:

  • FM Wave form demonstrate

Test Point:

  • 78

Power supply requirement:

  • 230V AC, 50 Hz.

On Board Switched Faults:

  • 8 Nos.
  • On Board Amplitude limiter with Amplitude control.
  • Input - Output and Test points provided on board.
  • A self contained Trainer.
  • Effect of noise on the detection of FM signal may be investigated.
  • Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections/ observation of waveforms.
  • Strongly supported by detailed Operating Instructions, giving details of Object, Theory, Design procedures, Report Suggestions and Book References.


  • 6 Kg. (Approx.)


  • W 412 x H 150 x D 310

Other Apparatus Required:

  • Cathode Ray Oscilloscope 20MHz.
  • Patch Cords
