Conditional short-circuit current is the value of the alternating current component of a prospective current, which a switch without integral short-circuit protection, but protected by a suitable short circuit protective device (SCPD) in series, can withstand for the operating time of the current under specified test conditions.
Another type of normalization is based on a measure of loudness, wherein the gain is changed to bring the average loudness to a target level. This average may be approximate, such as a simple measurement of average power (e.g. RMS), or more accurate, such as a measure that addresses human perception e.g. that defined by EBU R128 and offered by ReplayGain, Sound Check and GoldWave.
In telecommunications, maximum-ratio combining (MRC) is a method of diversity combining in which: . the signals from each channel are added together,; the gain of each channel is made proportional to the rms signal level and inversely proportional to the mean square noise level in that channel.
The unit dBov is defined in the ITU-T G.100.1 telephony standard such that the RMS value of a full-scale square wave is designated 0 dBov. [21] [22] All possible dBov measurements are negative numbers, and a sine wave cannot exist at a larger RMS value than −3 dBov without clipping. [21] This unit can be applied to both analog and digital ...
In electrical engineering, the average rectified value (ARV) of a quantity is the average of its absolute value.The ARV of an alternating current indicates which direct current would transport the same amount of electrical charge within the same period of time.

The EBU has suggested that the ITU should change the unit to LUFS, as LKFS does not comply with scientific naming conventions and is not in line with the standard set out in ISO 80000-8. Furthermore, they suggest the symbol for loudness level, k-weighted should be L k , which would make L k and LUFS equivalent when LUFS indicates the value of L ...
