(also NRZ)

Non-Return-to-Zero definition

NRZ, or Non-Return-to-Zero, operates as an encoding scheme in various data transmissions, especially in the context of cybersecurity and communication systems. It operates by representing each bit by a specified voltage level or signal state. Besides other encoding methods, NRZ doesn’t have transitions in the middle of a bit interval. Due to its simplicity, Non-Return-to-Zero encoding is used in a wide range of different industries and technologies.
