PCM / DPCM Demodulator

736112

4 PCM / DPCM Demodulator

Description

The PCM demodulator receives the transmitted data and the clock signal serially via a common data line (transmission channel) from the PCM modulator. The PCM demodulator converts the received data back into a PAM signal. Experiments on companding can be performed together with the compressor of the PCM modulator. The training panel also allows the demodulation of DPCM signals.

The device contains:

Serial/parallel converters
LEDs for simultaneous display of the bits set high
13-segment expander
D/A converter
Predictor

Technical data
