Delta is a plane company so
It is used to delay the modulation
if we need simple transmitter and receiver, if we need low bandwidth
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 modulation is extremely important for high-tech lives that humans live today. Delta modulation is basically analog to digital and digital to analog signal providers, allowing for radio communication devices such as TV remotes.
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..
Delta sigma modulation achieves "noise shaping" that essentially high-pass filters the quantization noise. This reduces the noise power in the baseband so that oversampling can access more bits of useful signal resolution than would be possible in the presence of the unfiltered noise.
The disadvantages of delta modulation are slope overload distortion and granular noise.
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.
