Rune,
I spent the day verifying unknown filters in my ham shack and documenting their performance using your new "Analysis" module (Tks !). I attached files earlier for typical high pass and low pass filter analysis screenshots . A typical BPF analysis screenshot is attached. There are four filter types I am familiar with: LPF, HPF, BPF and BSF (Band stop or Band reject), I tried selecting BPF analysis for the BSF chart but of course the parameters were out of bounds and no analysis was performed (see attachment).
I can do a low pass and high pass analysis on the BSF to derive the data for the cutoffs and bandwidth, but it would be more convenient if you would add BSF to your analysis module.
Best regards,
Herb
