Working Principle of Delta Modulation. Delta modulation process compares the present sample value to the previous sample value. Based upon the difference amplitude is going to be increased or decreased by step signal. If the amplitude is increased then step size increased by one step i.e., +Δ and bit 1 are generated.

How does delta modulation work?
The operation of a delta modulator is to periodically sample the input message, to make a comparison of the current sample with that preceding it, and to output a single bit which indicates the sign of the difference between the two samples. This in principle would require a sample-and-hold type circuit.
What is delta modulation in simple words?
Delta modulation is a process mainly used in the transmission of voice information. It is a technique where analog-to-digital and digital-to-analog signal conversion are seen. Delta modulation (DM) is an easy way of DPCM.
What are the applications of delta modulation?
Delta Modulation method is generally used for the encoding of signals from analog to PCM. It is also applied for signal conversion in television systems. One of the most critical applications of this technique is that it is used for real-time Signal Processing and database reduction in the ECG waveform.
What is delta modulation and how does it work how is it different from PCM?
Delta Modulation(DM):
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.
