RMS('Expression','Frequency'=50) and Eff('Expression','Frequency'=50)

Arguments

'Expression'	Signal or expression for which to determine the effective value
'Frequency'	Fundamental frequency

Description

This function calculates the so called "root mean square" value (or the effective value) of 'Expression' with a fundamental frequency of 'Frequency'.

e(n): Sample n of signal e ('Expression')

N: Number of samples in a period

Example

For an alternating voltage course with a frequency of 0.1 kHz, which is overlaid by a second AC voltage with 0.5 kHz, you can determine the effective value of the voltage for both frequencies by applying the function Eff with a second argument 0.1 or 0.5.

Note
	There is no difference between the functions RMS and Eff. Both functions are supported by ibaAnalyzer for compatibility reasons.
