because the data is sent as a series of digitally coded numeric values.
The difference between pulse code modulation and delta modulation is that pulse code modulation is a method of encoding audio information digitally while delta modulation is a method that converts analog to digital signal.
pulse code modulation method used a telephony.
Actually there are four:widthamplitudepositioncodeOf these four pulse code modulation is digital while the other three are analog.
Regenerative Repeater is used for the PCM (Pulse code modulation ) it amplifies the signal because the effect of the channel over the signal .
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.

PCM (Pulse Code Modulation)
It is a type of Pulse modulation as in PPM the position of pulse of carrier pulse train is varied in accordance with the modulating signal.

Delta modulation is not a type of quality conversion and runs on digital-to-analog, analog-to-digital. Differential pulse code modulation has a higher quality of conversion and runs on a 1-bit data stream.
PCM is Pulse Code Modulation, a modulation format used for recording audio in video recorders, computers, etc.
