Product Description

Frequency Modulation  Demodulation Trainer

FM Transmitter and Receiver Trainer has been designed with a view to provide practical and experimental knowledge of Frequency Modulation/ Demodulation technique as practically implemented in Analog Communication system on a SINGLE P.C.B. of size 300x400mm.

1. Object:
To Study Theory of Frequency Modulation & Demodulation:
01. Frequency Modulation via varactor / reactance Modulation.
02. Frequency Demodulation via Detuned Resonant / Ratio / Qudrature / Foster - Seeley / Phase locked loop detector.
03. Separate VCO circuit to demonstrate FM waveform.

2. Feature:
The board consists of the following built-in parts:
01. POWER SUPPLY : ± 12DC IC Regulated power supply.
02. FM Modulating signal generator : Sine wave
Frequency Range : 300 Hz to 3.4 Khz
Amplitude Range : 0 to 5 Vpp.
03. Modulator Type : Varactor modulator (With carrier frequency adjustment)
                               : Reactance Modulator (With carrier frequency adjustment)
04. Demodulator : Detuned resonant detector.
                           : Quadrature detector
                           : Foster - Seeley Detector
                           : Ratio Detector
                           : Phase locked loop Detector
05. Mixer/Amplifier : 1 No. (With gain adjustment) Allows FM input signal to be amplitude modulated by a noise input to demodulation.
06. Low pass Filter : 3.4 KHz. Cut of frequency Amplifier (with adjustable gain)
07. VCO Circuit : FM Wave form demonstrate
08 Test Point : 78
09. Power supply requirement : 230V AC, 50 Hz.
10. On Board Switched Faults : 8 Nos.
11. On Board Amplitude limiter with Amplitude control.
12. Input - Output and Test points provided on board.
13. A self contained Trainer.
14. Effect of noise on the detection of FM signal may be investigated.
