I have 2 bandpass filters in parallel with center frequencies of 350hz and 750hz.
Bode plotter only displays the 750hz filter not both.
Not sure what I'm dong wrong, maybe put a buffer on the output?
Shouldn't the plotter display both? sort of a double bump.

I got this to work by using a different filter topology.
I used a narrow band approach as opposed to the wider sallen-key I used in the first post.
However I would like to get the sallen-key one to work, any suggestions?
