Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This block calculates the root mean square and the phase angle of a single harmonic k of the input signal u over the given period 1/f, using the mean block.

Note: The output is updated after each period defined by 1/f.

Note:
The harmonic is defined by √2 rms cos(k 2 π f t - arg) if useConjugateComplex=false (default)
The harmonic is defined by √2 rms cos(k 2 π f t + arg) if useConjugateComplex=true
