Study Notes

Digital Line Coding

The main purpose of digital line coding is to convert the digital data into a signal that can be transmitted over a communication channel.

Transmission Bandwidth

The transmission bandwidth must be at least twice the maximum frequency component of the signal to avoid signal distortion.

Transmitted Power

A key requirement for the transmitted power in line-coding is that it should be maintained at a minimum level to reduce the effects of attenuation and noise.

Error Detection and Correction

Line coding should possess the capability of error detection and correction to ensure reliable data transmission.

Bipolar Case

In a bipolar case, when a signal error occurs, the signal switches to the opposite polarity to indicate the error, providing a way to detect errors.
