Description
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.

Research direction
Start by reproducing the Wavebuilder case with epoch type noise, duration 1000, amplitude 1, low pass 100, and high pass 10, comparing filter orders 5 through 8. Check the same behavior in the butterworth SF operation; done means the expected relationship between filter order and output curves is established and covered by a regression check.
