Wavebuilder: Outputs the same noise curve for different filter orders
Opened this issue · 2 comments

For epoch type noise, duration 1000, amplitude 1, low pass 100, high pass 10 we get the same curves for filter order 5 and 6, and 7 and 8 and so on.
I guess is this is a property of the created filter.
Same issue with the butterworth
SF operation.

Asked WM for help.

WM confirmed that the order for bandpass filters will be made one larger if it is odd as the internal implementation requires an even value.
Remedies:
- Fix the order up for the user with a warning message
- Don't allow to input odd numbers for bandpass/bandstop in the Wavebuilder GUI
- SFH_Assert in SF for butterworth
