PCM / DPCM Modulator

The sampled, discrete-time signal is quantized and coded in the PCM modulator. A fully digital (discrete time and value) signal is generated from the analog input signal of the PAM modulator. The PCM modulator allows an investigation of linear and non-linear quantizing. The training panel also allows an investigation of DPCM (difference pulse code modulation) signals.
