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.

The device contains:

• 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
