Compare pulse code modulation and delta modulation?
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..
What are the application of delta modulation in speech synthesis?
it is used in voice transmission,to active vibration control and is used in channel vocoder
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.
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
Where is adaptive delta modulation used?
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
Where is delta modulation used?

What is use of time delay in adaptive delta modulation?
It is used to delay the modulation
What is Adaptive delta modulation?
Adaptive delta modulation is a analog-to-digital and digital-to-analog conversion technique which is primarily used for voice transmission data and can be used for multiple purposes.
Why do you use sigma delta modulation instead of adaptive delta modulation?
if we need simple transmitter and receiver, if we need low bandwidth

What are Advantages 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.
What are Disadvantages of Adaptive delta modulation?
There are two major disadvantages of delta modulation: 1. Slope overload distortion: occurs when modulating signal varies faster than counter recovered signal. 2. Granular noise: occurs when variation in modulating signal is smaller than step size.
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.
Why you call delta of delta modulation?
because you do.
