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
