Abstract :
The delta modulation (DM) of signals which are already in digital form is of interest in a variety of signal-processing applications. It is shown that a delta modulator for digital inputs may be usefully interpreted as a process of slope bias, accumulation, and overflow detection leading to designs which are simpler than those based on analog techniques. Applications are discussed including a divider for delta-modulated signals and an averager of K delta-modulated inputs.
