return to zero
(foldoc) | Return To Zero
A class of encoding methods for physical
circuits in which the carrier (current, voltage) returns to
zero after each transmitted bit, i.e. the data is carried in
pulse width or polarity, not in the level of the signal.
Contrast NRZ.

NRZI
(NRZI) A recording method used for 9-track {magnetic
tapes} (200 and 800 BPI) where a zero is represented by a
change in the signal and a one by no change.
NRZI is also used extensively in SDLC communications.
VTAM has a parameter NRZI=YES|NO.
Compare Phase Encoded, GCR.
