IT-4102 is the training system which is designed to give the student a deep understanding of recovery techniques of Amplitude Modulation signal. Receiver is designed similar to that of a commercial Radio Receiver.  It demonstrates Super heterodyne Receiver with Automatic Gain Control (AGC) Technique to demodulate the received AM DSB signal. AM SSB signal is received using product detector.
