I sometimes want a wider or more narrow bandwidth in my bandpass filter. I couldn't find anything by Googling. Is this possible?
[Virus TI] Adjusting the bandwidth of the bandpass filter
-
-
You can only adjust the bandwidth of the first filter when using a BP.
To do so select ser6 or ser4 in the filter routing section. Ser6 will change filter one into a 4pole BP, and Ser4 will change filter one into a 2pole BP.
HTH.

OK so these poles in fact adjust the "tightness" of the filters. The more poles, the steeper the curves right?
-
Correct, more poles equals steeper curves.

This is correct. The bandwidth of the filter itself cannot be changed though, only whether you want to use a 12dB or 24dB version for Filter 1 with the routing settings.
Best wishes,
