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..

Difference between analog modulation and digital modulation?
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.
How regenerative repeater work in pulse code modulation?
Regenerative Repeater is used for the PCM (Pulse code modulation ) it amplifies the signal because the effect of the channel over the signal .

What is the difference between pulse code and pulse amplitude in brief and concise terms?
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).
What is the second step in the pulse code modulation process?
digital converter extracts samples of analog signal from input siganl digital converter quantizes analog sample and assignes a binary numbervalue to it digital coanverter encodes a quantized analog signal to transmit it across a digital network
What is the difference between pulse code modulation and 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.
Difference between delta modulation and differential pulse code 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.
What modulation is used in telegraphy system?
pulse code modulation method used a telephony.
What are the three types of pulse modulation?
Actually there are four:widthamplitudepositioncodeOf these four pulse code modulation is digital while the other three are analog.
