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.
what is delta modulation and compare with pcm
There is no difference.
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..
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.
Frequency modulation, as the name suggests, modulates the carrier by changing the frequency of the signal emitted. Pulse width modulation, changes the on-time of a square wave, but leaves the frequency of the carrier wave unchanged. So, in frequency modulation, the frequency will vary between, say, 80kHz and 120kHz with a constant power level, but in pulse width modulation, the frequency will stay at 100kHz, but the on-time (the length of each pulse) will vary, hence the power level will vary accordingly.
PAM-pulse Amplitude Modulation It encodes information in the amplitude of a sequence of signal pulses. PPM-Pulse Position modulation PWM-Pulse Width Modulation.It results in variation of average waveform.
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.
advantage of pulse position modulation
It signals the difference between successive sample sizes

The first step in the Pulse Code Modulation is the Sampling Process!

There are 3 main types of digital pulse modulation:Pulse time modulation (PTM), somewhat similar to analog phase modulation.Pulse width modulation (PWM), the width of the pulse represents the signal.Pulse code modulation (PCM), serial transmission of binary bits forming numeric or character codes that represent the signal.All of these can be modulated on an RF carrier using any of the standard modulation techniques: AM, FM, Phase Modulation, etc. One advantage with AM digital pulse modulation techniques over AM analog is that the carrier can be 100% modulated, which cannot be done with analog, thereby allowing significant reductions in transmitter power without loss of coverage range. Sometimes FM digital pulse modulation techniques are referred to as Frequency Shift Keying (FSK). A very complex method of combining Phase Modulation and AM to increase the bit density of digital pulse modulation on an RF carrier is called Quadrature Amplitude Modulation (QAM).
in normal person there is no difference between radial pulse and carotid pulse but in ill or sick person it may vary.
NO. the difference between the Apical and Radial pulse is known as the pulse deficit. There should be some difference between the twon.
pulse Amplitude modulation is used for efficient transmission of data interms of pulses rather than continuous
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
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).
