Non-Return-to-Zero (NRZ) is a type of data modulation used to send digital signals where the polarity of the 0s and 1s are different; positive for 0 and negative for 1. This technique is widely used in computer networking and digital communication systems.
NRZ is simple to implement and cost-effective, making it a common choice for transmitting digital data. However, it has some drawbacks, such as the lack of synchronization and the limited bandwidth compared to other modulation techniques like Phase-shift keying (PSK) and Quadrature amplitude modulation (QAM).
Overall, NRZ is a significant breakthrough in the digital domain that deals with data transmission. Understanding its concepts and applications is essential for anyone working in the field of computer networks and digital communication systems.
