The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or the square of the function that defines the continuous waveform.
A Kanal is a unit of area, equivalent to 5445 square feet or one-eighth of an acre.It is mainly used in Punjab province of Pakistan.Under British rule the Marla and Kanal were standardized so that the Kanal equals exactly 605 square yards or 1/8 acre; this is equivalent to about 505.857 square meters.
In fluid dynamics, normalized root mean square deviation (NRMSD), coefficient of variation (CV), and percent RMS are used to quantify the uniformity of flow behavior such as velocity profile, temperature distribution, or gas species concentration. The value is compared to industry standards to optimize the design of flow and thermal equipment ...
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.
True RMS provides a more correct value that is proportional to the square root of the average of the square of the curve, and not to the average of the absolute value. For any given waveform , the ratio of these two averages is constant and, as most measurements are made on what are (nominally) sine waves, the correction factor assumes this ...
The relationship between dBm0 and dBFS is unfortunately ambiguous. It depends how RMS and peak levels in dBFS are defined. The ambiguity is if a full scale sinusoidal in a digital system is defined to have an RMS level of −3 dBFS RMS or if it should be defined to have a RMS value of 0 dBFS RMS, equal to the dBFS peak
Computer hardware and software standards are technical standards instituted for compatibility and interoperability between software, systems, platforms and devices.
The human ear responds quite differently to clicks and bursts of random noise, and it is this difference that gave rise to the CCIR-468 weighting curve (now supported as an ITU standard), which together with quasi-peak measurement (rather than the rms measurement used with A-weighting) became widely used by broadcasters throughout Britain ...
