I have been working on an updated version of the gyrator bandpass filter calculator that has a chart with instant updating!
After more than 16 revisions, I am getting closer to something that I like, and which I think will be useful. Just for readers of this blog, you can try out the beta version at:

This probably a temporary link so don’t bookmark it yet. The intro paragraph with schematic is not on the page yet but I will put it back once I get to the final release.
