Delta modulation works by transmitting the difference between consecutive samples. The transmitter quantizes this difference, and the receiver integrates these quantized differences to reconstruct the original signal. The process in the transmitter can be thought of as a form of differentiation (change in signal), and the process in the receiver is integration (summing the changes).
The demodulation of a delta-modulated signal is achieved by differentiation sampling integration band-pass filtering
