Definitions for "NRZ"
Keywords:  nonreturn, zero, polarity, snr, encoded
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.
