Differential Pulse Code Modulation
Experiments:
- Employing a particular coding scheme distortion (Fidelity) can be measured with different input wave shapes.
- Selection of multiplier coefficient of present and previous samples with respect to the slope of the input signal
- Observe the DPCM output waveform for a given input and its reconstruction at decoder.
