In alternating-current power transmission and distribution, the product of the rms voltage and amperage, i.e., the apparent power, multiplied by the power factor, i.e., the cosine of the phase angle between the voltage and the current.
Note: Only effective power, i.e., the actual power delivered to or consumed by the load, is expressed in watts. Apparent power is properly expressed… (Read More →)

1. The power supplied to an antenna multiplied by the antenna gain in a given direction.
Note 1: If the direction is not specified, the direction of maximum gain is assumed.
Note 2: The type of reference antenna must be specified.
2. The product of the power supplied to the antenna and its gain relative to a half-wave dipole in… (Read More →)

Synonym effective transmission rate.

The rate at which information is processed by a transmission facility.
Note 1: The effective transmission rate is calculated as (a) the measured number of units of data, such as bits, characters, blocks, or frames, transmitted during a significant measurement time interval divided by (b) the measurement time interval.
Note 2: The effective transmission rate is usually expressed as a… (Read More →)

A property of a Target of Evaluation representing how well it provides security in the context of its actual or proposed operational use [ITSEC].

In data communications, the ratio of (a) the time to transmit a text automatically at a specified modulation rate to (b) the time actually required to receive the same text at a specified maximum error rate.
Note 1: All of the communication facilities are assumed to be in the normal condition of adjustment and operation.
Note 2: Telegraph communications may… (Read More →)
