Keying or digital modulation applies to transmitting a digital signal over an analogue passband channel. When a digital signal is to be transmitted over an analogue baseband channel, the modulation technique is termed line coding.

What is meant by line coding?
The process of converting binary data into a sequence of bits of the digital signal is known as Line coding. It is also known as digital PAM formats.
What are the different types of line coding?
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 line coding and block coding?
Out of which Line coding is always needed, block coding and scrambling may or may not be needed. Block coding helps in error detection and re-transmission of the signal. It is normally referred to as mB/nB coding as it replaces each m-bit data group with an n-bit data group (where n>m).
Which line coding is best?
Manchester encoding. Manchester encoding is a widely used line coding scheme that embeds timing information in the transmitted signal.
