The difference between the instantaneous frequency of a digital signal and the long-term average frequency of that signal. 2. An unintentional deviation from the nominal frequency value.
Industry:Telecommunications
The difference between the frequency of a source and a reference frequency.
Industry:Telecommunications
The difference between local clock time or value and a designated reference clock time or value. Note: Subtracting the clock difference from the local clock brings the local clock into agreement with the reference clock.
Industry:Telecommunications
The difference between available signal power and the minimum signal power needed to overcome system losses and still satisfy the minimum input requirements of the receiver for a given performance level. Note: System power margin reflects the excess signal level, present at the input of the receiver, that is available to compensate for (a) the effects of component aging in the transmitter, receiver, or physical transmission medium, and (b) a deterioration in propagation conditions. Synonym system power margin.
Industry:Telecommunications
The difference between a computed, estimated, or measured value and the true, specified, or theoretically correct value. 2. A deviation from a correct value caused by a malfunction in a system or a functional unit. Note: An example of an error is the occurrence of a wrong bit caused by an equipment malfunction.
Industry:Telecommunications
The difference between a color and a specified reference color having a specified chromaticity and an equal luminance.
Industry:Telecommunications
The dialogue between two information systems for synchronizing, identifying, and authenticating themselves to one another.
Industry:Telecommunications
The deviation of the frequency of an oscillator from its nominal constant frequency, normalized to the nominal frequency.
Industry:Telecommunications
The deviation of an electromagnetic wavefront from the path predicted by geometric optics when the wavefront interacts with, i.e., is restricted by, a physical object such as an opening (aperture) or an edge. Note: Diffraction is usually most noticeable for openings of the order of a wavelength. However, diffraction may still be important for apertures many orders of magnitude larger than the wavelength.
Industry:Telecommunications
The deviation of a dependent variable with respect to a reference function.
