What is NRZ encoding?

Non-return to zero encoding is commonly used in slow speed communications interfaces for both synchronous and asynchronous transmission. Using NRZ, a logic 1 bit is sent as a high value and a logic 0 bit is sent as a low value (the line driver chip used to connect the cable may subsequently invert these signals).

Furthermore, what is a line coding?

Digital Line Coding is a special coding system chosen to allow transmission to take place in a communications system. The chosen code or pattern of voltage used to represent binary digits on a transmission medium is called line encoding. The types of line encoding are polar, unipolar and bipolar.

What do you mean by line coding?

In telecommunication, a line code is a code chosen for use within a communications system for transmitting a digital signal down a transmission line.
