Question

Briefly explain the difference between modulating and encoding?

Answer 1

Answer:

Encoding is the process in which the digital or analog data are converted into digital signal. Encoding are used for efficient transmission and storage purpose by putting in the form of sequence of various number and characters.

There are basically three types of encoding:

• Semantic encoding
• Visual encoding
• Acoustic encoding

Modulating is the process of encoding the information in a transmitted signal and converting the digital or analog data into analog signals. It is widely used in long distance communication. In modulating process, modulator is the device that are capable of modulating carrier signal.
