See zero-bit insertion.

The elimination of nonsignificant zeros from a numeral.

Synonym zero dBm transmission level point.

A bit-stuffing technique used with bit-oriented protocols to ensure that six consecutive "1" bits never appear between the two flags that define the beginning and the ending of a transmission frame.
Note: When five consecutive "1" bits occur in any part of the frame other than the beginning and ending flag, the sending station inserts an extra "0" bit. When… (Read More →)

In a single-mode optical fiber, the rate of change of dispersion, with respect to wavelength, at the fiber's zero-dispersion wavelength.
Note 1: In silica-based optical fibers, the zero-dispersion wavelength occurs at approximately 1.3 m, but this wavelength may be shifted toward the minimum-loss window by the addition of dopants to the fiber material during manufacture.
Note 2: Doubly and quadruply… (Read More →)

1. In a single-mode optical fiber, the wavelength or wavelengths at which material dispersion and waveguide dispersion cancel one another.
Note: In all silica-based optical fibers, minimum material dispersion occurs naturally at a wavelength of approximately
1. 3 m. Single-mode fibers may be made of silica-based glasses containing dopants that shift the material-dispersion wavelength, and thus, the zero-dispersion wavelength, toward… (Read More →)

A decoder that yields an analog level of 0 dBm at its output when the input is the digital milliwatt signal. [47CFR]
Note: The signal is a 1-kHz sine wave.

To fill unused storage locations in an information system (IS) with the representation of the character denoting "0". [INFOSEC-99]

To remove or eliminate the key from a crypto-equipment or fill device. [INFOSEC-99]

Electronically stored data that have been degaussed, erased, or overwritten. [After X9.17]
