Amplitude modulation is implemented by means of a variable trans conductance four quadrant multiplier designed around CA3086. On board carrier and modulating signals along with power supplies are provided. A detector and a low pass filter are provided to demodulate the signal. Modulation Index, Depth of Modulation, etc., are studied using this trainer.HARDWARE SPECIFICATION1) +/-12V/350 mA DC Power Supply 2) Carrier Generator 100 KHz 3) Modulating signal Generator at 1 KHz 4) Amplitude Modulator 5) Amplitude Demodulator 6) Set of 4mm Patch Chords & Manual
