Learn what Non-Return-to-Zero (NRZ) is, how NRZ works, its applications, advantages, and limitations. Click for more information now!The binary signal is encoded using rectangular pulse-amplitude modulation with polar NRZ (L), or polar non-return-to-zero-level code. In telecommunications, a non-return-to-zero (NRZ) line code is a binary code in which ones are represented by one significant condition, usually a positive voltage. NRZ, NRZI, and Manchester are popular serial encoding mechanisms. Find out how they differ from each other. This article is part of the Communication Series: What's the Difference: Serial Communications 101 Members can download this article in PDF format. What Is NRZ and How Does It Work?This article compares RZ (Return-to-Zero) and NRZ (Non-Return-to-Zero) line coding techniques, highlighting the differences between their pulse shapes. NRZ is implemented with two levels: A VOH Mark state, which represents a ' 1 ' data bit, and a VOL Space state, which represents a ' 0 ' data bit.
