In a waveguide, a time-varying field having an amplitude that decreases monotonically as a function of transverse radial distance from the waveguide, but without an accompanying phase shift.
Note 1: The evanescent field is coupled, i.e., bound, to an electromagnetic wave or mode propagating inside the waveguide.
Note 2: The evanescent field is a surface wave.
Note 3: In fiber… (Read More →)

A mode of the evanescent field.

See parity, parity check.

1. An occurrence or happening, usually significant to the performance of a function, operation, or task.
2. In Integrated Services Digital Networks (ISDN), an instantaneous occurrence that changes at least one of the attributes of the global status of a managed object.
Note: An event (a) may be persistent or temporary, thus allowing for functions, such as surveillance, monitoring, and… (Read More →)

Enhanced Variable Rate Codec

Abbreviation for electronic warfare.

A method of receiving either amplitude- or phase-modulated signals in which method the carrier is separated from the sidebands, filtered and amplified, and then combined with the sidebands again at a higher level prior to demodulation. Synonym reconditioned carrier reception.

In data transmission, the condition assumed by a device when it receives a command that it cannot execute.
