Here's something i dreamed up whilst tinkering with an AP All Pass circuit. Initially it occurred to me that this technique "might" be workable as a HPF High Pass Filter as shown ? For eg a rumble filter etc etc.
The circuit i've simmed seems to work anyway ! The component values are idealised for my convenience only.
I said etc in the title, because i suppose the AP could be configured as a LPF Low Pass Filter also. Therefore i expect a BP BandPass might work too.
As is, the design is for audio, but if workable then maybe other disciplines might be achievable as well ?
What benefits there might be, if any, over traditional methods i'm not sure ?
See what you think 😉

I was looking at this the other day. Damned if I can remember where tho, but certainly using all pass as the basis for a parametric eq has been used before. If I can remember where it was will post it.
