Compare pulse code modulation and delta modulation?
delta modulation refers to the procedure of encoding and thereby transmitting only the difference between consecutive samples instead of sending each of the samples themselves. This method is useful only when the vaiation in the amplitude of the signal is small, otherwise, it leads to a phenomenon called "slope overload".Pulse code modulation is the procedure where each of the levels of an analog signal is assigned a value closest ro a quantizer level used to quantize the signal...Another method of PCM that can be confused with Delta Modulation is the D(ifferential)PCM. Here, the difference between the signals is encoded based on its magnitude..
Why do you use sigma delta modulation instead of adaptive delta modulation?
if we need simple transmitter and receiver, if we need low bandwidth

What is adaptive dpcm?
Adaptive differential pulse-code modulation(ADPCM) is a variant of differential pulse-code modulation (DPCM) that varies the size of the quantization step, to allow further reduction of the required bandwidth for a given signal-to-noise ratio.Typically, the adaptation to signal statistics in ADPCM consists simply of an adaptive scale factor before quantizing the difference in the DPCM encoder.[1]ADPCM was developed in the early 1970s at Bell Labs for voice coding, by P. Cummiskey, N. S. Jayant, and James L. Flanagan.[2]susheelonline.com
What are Disadvantages of Adaptive delta modulation?
There are two major disadvantages of delta modulation: 1. Slope overload distortion: occurs when modulating signal varies faster than counter recovered signal. 2. Granular noise: occurs when variation in modulating signal is smaller than step size.
