That power available at a specified output of a device under specified conditions of operation.
Note: Rated output power may be further described; e.g., maximum rated output power, average rated output power.

A measure for the assurance that may be held in a Target of Evaluation, consisting of a reference to its security target, an evaluation level established by assessment of the correctness of its implementation and consideration of its effectiveness in the context of actual or proposed operational use, and a confirmed rating of the minimum strength of its security mechanisms… (Read More →)

Synonym maximal-ratio combiner.

A geometric representation of a lightwave by a line normal to the electromagnetic wavefront; i.e., in the direction of propagation of the wave. [FAA]

Synonym geometric optics.

A mathematical statement, usually applied to frequency distributions of random variables, for the case in which two orthogonal variables are independent and normally distributed with unit variance.

In electromagnetic wave propagation, phase-interference fading caused by multipath, and which may be approximated by the Rayleigh distribution.

Of an electromagnetic wave propagating in a material medium, scattering caused by refractive-index inhomogeneities that are small compared to the wavelength.
Note 1: Rayleigh scattering losses vary as the reciprocal of the fourth power of the wavelength.
Note 2: Ionospheric scattering is caused partly by Rayleigh scattering.

Acronym for Regional Bell Operating Company.

Abbreviation for radio common carrier.
