What is called line coding?

Line coding is the process of converting digital data to digital signals. By this technique we converts a sequence of bits to a digital signal. At the sender side digital data are encoded into a digital signal and at the receiver side the digital data are recreated by decoding the digital signal.

What is line coding why line codes are essential?

A line code is the code used for data transmission of a digital signal over a transmission line. This process of coding is chosen so as to avoid overlap and distortion of signal such as inter-symbol interference.

What is line coding and its type?

The waveform pattern of voltage or current used to represent the 1s and 0s of a digital signal on a transmission link is called line encoding. The common types of line encoding are unipolar, polar, bipolar and Manchester encoding. Line codes are used commonly in computer communication networks over short distances.

What is the difference between line coding and block coding?

It can be done in two ways, line coding and block coding. For all communications, line coding is necessary whereas block coding is optional. The process for converting digital data into digital signal is said to be Line Coding. Digital data is found in digital format, which is binary bits.
