FM Transmitter & Receiver Trainer
Model No. HV-EXP2222
FM transmitter and receiver trainerhas been designed with aview 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 :0to 5Vpp. 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 : 1No. (With gain adjustment) Allows FM input signal to be amplitude modulated by anoise input to demodulation. 06.Low pass Filter : 3.4 KHz.:Cut of frequency Amplifier (with adjustable gain) 07.VCO Circuit: FM Wave form demonstrate 08Test Point :78 09.Power supply requirement : :230VAC, 50 Hz. 10.On Board Switched Faults:8Nos. 11.On Board Amplitude limiter with Amplitude control. 12.Input -Output and Test points provided on board. 13.Aself contained Trainer. 14.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. Weight :6Kg. (Approx.)
