Describe Adaptive Delta Modulation (ADM) and explain how it reduces distortion.

Worked SolutionAI Assisted

Answer

ADM: Adaptive step $\Delta[n+1]=\Delta[n]\cdot K$ if consecutive bits same (slope overload) increase, if alternating decrease. Handles steep and flat. SNR +10dB vs DM, wider dynamic range.
