To overcome the quantization errors due to slope overload and granular noise, the step size (δ) is made adaptive to variations in the input signal x(t).
Particularly in the steep segment of the signal (t) , the step size is increased .When the input is varying slowly , the step …

Delta modulation is a Differential Pulse Code modulation (DPCM) technique in which the difference signal is encoded into a single bit.
Delta modulation provides a staircase approximation of the input sampled signal where only one bit per sample is transmitted.
This one bit is sent by comparing the present sample …
