Delta modulation was introduced in the 1940s as a simplified form of pulse code modulation pcm, which required a difficulttoimplement analogtodigital ad converter. Differential pulse code modulation dpcm circuit working its. In pcm systems, a waveform codec takes samples of an analogspeech waveform and encodes them as modulated pulses, represented by logic 1 high and logic 0 low. This technique samples the analog signal and then quantizes the difference between the sampled value and its predicted value, then encodes the signal to form a digital value.
