Frequency Domain Graphing Analysis
The
Frequency Domain
data capture view shown in
has an
FFT Filter Parameters
section
which allows removal and inclusion of selected frequency bins. The default filter settings are to remove 25
bins around the detected fundamental, remove 25 bins at DC, and include 5 harmonics of the detected
fundamental.
NOTE:
The GUI simply determines the fundamental to be the bin with the highest power.
The
No. of Harmonics
is applied differently to the SNR computation. For this calculation, the
No. of
Harmonics
value determines the number of bins to remove from the calculation instead of include.
