A binary encoding scheme in which ones and zeroes are represented by opposite and alternating high and low voltages and where there is no return to a zero (reference) voltage between encoded bits.
A data transmission technique where a polarity level, high or low, represents a logical 1 or 0.
Non Return to Zero. A coding scheme that is polarity sensitive, usually a low signal level means logical '0' and high level means logical '1'. This coding scheme suffers the disadvantage that it contains frequency components from DC and is thus unsuitable.
Non Return to Zero. Indicates a type of signal which has a (+) positive state and a (-) negative state, but no zero-state.
Nonreturn-to-Zero SNR Signal-to-Noise Ratio
The optical line coding used in SONET systems. A one or zero is designated by constant levels of opposite polarity.
Non-Return to Zero) A binary encoding scheme representing ones and zeroes by opposite and alternating high and low voltages, in which there is no return to a zero (reference) voltage between encoded bits.
Abbreviation for non-return to zero. A common means of encoding data that has two states termed "zero" and "one" and no neutral or rest position.
Storage products. No Return to Zero : Phase coding, used particularly with magnetic tape drives and hard disk drives.
Nonreturn to zero. Signaling method that does not automatically return to a neutral state after each bit transmission.
nonreturn to zero. NRZ signals maintain constant voltage levels with no signal transitions (no return to a zero-voltage level) during a bit interval. Compare with NRZI.
A digital signaling technique in which the signal is at a constant level for the duration of time.
