Mô tả
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
