Explain why Adaptive Delta Modulation (ADM) may be required.
What will be an ideal response?
To reduce slope overload, the step size must be increased. However, increasing the step size will result in higher granular noise. Therefore, improving one problem in DM will result worsening another problem. Employment of a controllable step size mechanism that is sensitive (adopts itself) to the slope of the sampled signal in DM will resolve this problem. This type of DM is called Adaptive Delta Modulation (ADM).
