delta modulation refers to the procedure of encoding and thereby transmitting only the difference between consecutive samples instead of sending each of the samples themselves. This method is useful only when the vaiation in the amplitude of the signal is small, otherwise, it leads to a phenomenon called "slope overload".Pulse code modulation is the procedure where each of the levels of an analog signal is assigned a value closest ro a quantizer level used to quantize the signal...Another method of PCM that can be confused with Delta Modulation is the D(ifferential)PCM. Here, the difference between the signals is encoded based on its magnitude..
it is used in voice transmission,to active vibration control and is used in channel vocoder
The main limitation of a sold state microwave device is its surroundings. The microwave tower needs to be tall enough to overcome trees and other objects getting in the way of transmission.
the modulation system is of FM
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.
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
The delta modulation transmits only one bit for one sample. Thus the signaling rate and transmission channel bandwidth is quite small for delta modulation. The transmitter and receiver implementation is very much simple for delta modulation. There is no analog to digital converter involved in delta modulation. The disadvantages of delta modulation are slope overload distortion and granular noise. These are the two drawbacks of delta modulation.

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.
because you do.
Delta is a plane company so

Please define which limitation is being addressed here.
if we need simple transmitter and receiver, if we need low bandwidth
It is used to delay the modulation

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.
