In Delta Modulation step size is fixed for the whole signal. Whereas in Adaptive delta modulation, the step size varies depending upon the input signal. The slope overload and granular noise errors which are present in delta modulation are not seen in this modulation.

Why adaptive delta modulation is better than delta modulation?
Adaptive delta modulation offers extremely high performance. This technique decreases the need for correction circuits in radio design and error detection. Dynamic range is high since the variable step size covers a large range of values. Slope overload error and granular error are not seen.
What is Adaptive delta modulation definition?
Adaptive delta modulation is a delta modulation system where the step size of the DAC is automatically varied, depending on the amplitude characteristics of the analog input signal.
What are the different types of delta modulation?
Derived forms of delta modulation are continuously variable slope delta modulation, delta-sigma modulation, and differential modulation.
How adaptive delta modulation is different than differential PCM modulation technique?
It uses one bit PCM code to realize digital transmission of analog signal. With delta modulation, instead of transmit a coded illustration of a sample solely one bit is transmitted, that merely indicates whether or not the sample is larger or smaller than the previous sample.
