The pulse amplitude modulation (PAM) scheme is used as an intermediate step in the creation of pulse code modulation (PCM). In PAM, the amplitude of discrete pulses represents the sampled values of the analog signal. These amplitude levels are then quantized and encoded into a binary format to produce the final PCM signal. This process enables the efficient digital representation of analog information for transmission and storage.
Analog Pulse modulation is discreet in time but the formation is transmitted in continuous form. In digital pulse modulation, not only the time axis is discreet but the information is also in digital form. Examples of Analog PM are PAM and PTM i.e pulse amplitude and pulse time modulations respectively. Examples of Digital PM are PCM and PDM i.e pulse code and pulse delta modulations respectively.
In pulse amplitude modulation (PAM), you send a single pulse of a certain height (amplitude) that represents the value of the sampled signal at that time. With pulse code modulation (PCM), you take the same sampled value, but now represent that value by N bits, where N is the number of quantized regions. Why send a whole bunch of bits instead of just a single pulse? Because PCM performs better in situations of higher noise (AWGN).
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.

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.
