This trainer kit is designed to study the fundamentals of Differential Pulse Code Modulation, Adaptive Pulse Code Modulation and Demodulation Techniques, principles of Differential Pulse Code Modulation, such as Sampling, Quantizing and Coding can be studied. Differential Pulse Code Modulation (DPCM) is a technique of waveform coding, which involves the use of a predictor. Adaptive Pulse Code Modulation technique attempts to code signals without any knowledge about how the signal was created.
