Merits of Adaptive Delta Modulation:

• The signal to noise ratio of ADM is better than that of DM because of the reduction in slope overload distortion and idle noise.
• Because of the variable step size , the dynamic range of ADM is wider than DM.
• Utilization of bandwidth is better in ADM than DM.

Demerit of Adaptive Delta Modulation:

• For a relatively constant magnitude of input signal x(t), the system will produce high granular noise.
• Lower bit rate than PCM
