Our Product / Services
We offer a complete product range of Communication Engineering Training Boards
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.
