Definition
Non Return to Zero (NZR)
Non-Return-to-Zero (NRZ) encoding is a binary transmission encoding in digital communication and data storage.
In NRZ encoding, the signal maintains a constant voltage level for the duration of the bit period, with no return to baseline (zero) level between bits.
The encoding directly represents binary data with specific voltage levels assign to binary and .
Variants
There are various types of NRZ, such as NRZ-L, NRZ-M and NRZ-S.
