PCM / DPCM Modulator

736102

4 PCM / DPCM Modulator

Description

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.

Features:

8-bit A/D converters
LEDs for simultaneous display of all active bits
Parallel/serial converters
13-segment compressor
Predictor
Clock control
DC voltage source for coding experiments
Device is compaible with 736112 PCM / DPCM Demodulator
