IT-4202 Time Division Multiplexing Transceiver Trainer

This trainer is an extension of the concepts learned in Signal Sampling & Reconstruction trainer. Technique relating to TDM is explored. Sampled signals are Pulse Amplitude Modulated and multiplexed. Received signal is then demultiplexed and demodulated to form original transmitted signals. Necessary components are on board like, counters and analog signal generators.
