Encoding: The way in which the computer data is represented is known as encoding, there are several encoding techniques (Unipolar, Bipolar and Biphase).
Modulation: Modulation is the method of changing some of the characteristics of the message signal so that it can be transmitted to comparatively large distance without(least) getting affected by noise or unwanted signals.

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.
What is difference between decoding and encoding?
encoding
What is the difference between NRZ L and Manchester encoding?
For NRZ we require large bandwidth,because transition will not occur in middle of bit.whereas in Manhaster encoding transition will occur middle of the bit so Data rate = Modulation rate/2 Regards, Dilip Prajapati
What is the difference between space vector modulation and pulse width modulation?
There is no difference.
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
What encoding or modulation technology does 802.11a use?
OFDM

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 is difference between encoding and modulation?
encoding means to encode the data generally it uses for security purposes, we encode the data by using some mathematics operations so that no other could get the information. in modulation we also change the input but it is used for the send the signals to a long way. the week frequency signals can not travel to the long way so we superimpose the week frequency signals to the high frequency signals so that it could reach at it destination. the reverse process of encoding is decoding and the reverse process of modulation is demodulation so that we can get our data in a original form.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
What is Modulation and what is the aim of modulation?
Modulation is any of several means of encoding an information carrying signal onto a carrier of fixed frequency. The purpose is to allow the information to be transported long distances.
Difference between encoding and batch encoding?
Encoding simply refers to the "encoding" of one single file. Batch encoding refers to setting up several files to encode one after another. It's basically automated.
