1. Specify the algorithm that is followed to generate delta-modulated signal waveform.

2. Delta modulation is a special case of differential PCM. Carry out the comparative study of similarities among these two techniques.

3. What happens when the variations in adjacent samples of the analog signal are quite fast as compared to the step-size in delta modulation? Draw an appropriate illustration to depict this phenomenon.

4. Specify two unique features offered by delta modulation.
