Differential pulse-code modulation (DPCM) is a signal encoder that uses the baseline of pulse-code modulation (PCM) but adds some functionalities based on the prediction of the samples of the signal. The input can be an analog signal or a digital signal. If the input is a continuous-time analog signal, it needs to be sampled first so that a discrete-time signal is the input to the DPCM encoder. WebDifference between DM and ADM: DM stands for delta modulation while in ADM stands for adaptive delta modulations. Both are used for only one bit per one sample, In Delta, the modulation step size is kept fixed and cannot be varied while in Adaptive delta modulation according to signal variations step sizes varies. kansas educational standards
