Variable: FFTAverageType
Specifies how DIAdem averages the amplitudes.
| Definition | FFTAverageType, Enumeration variable | ||||||||||||||||
Enumeration variable with the following selection terms
|
Valid settings
No |
No averaging |
arithmetic |
DIAdem provides all n amplitude values to be averaged with the same weight factor 1/n. |
exponential |
The weighting factors increase towards the end of the averaging process exponentially. |
PeakMin |
DIAdem determines for each channel index the smallest value for all amplitudes |
PeakMax |
DIAdem determines for each channel index the greatest value for all amplitudes |
PeakMinMax |
DIAdem determines for each channel index the smallest and the greatest value for all amplitudes |
MinMaxAverage |
DIAdem determines for each channel index the smallest and the greatest value and also the arithmetic mean of all amplitudes. |
If you calculated standard amplitudes or octave amplitudes in a time signal analysis, DIAdem averages the amplitudes types separately. DIAdem only saves the mean values in the result channel.
To determine the transfer functions spectrum H1 and spectrum H2 DIAdem averages arithmetically. You also can average the phases of the transfer functions of this type. This averaging is arithmetic too.
