| May 11, 2023 at 18:17 | comment | added | periblepsis | @GrangerObliviate I think you summarized the issues well. Gain impacts value spread, just as you say. For example, going from a gain of 1 to a gain of 2 may cause the capacitor value spread to go from 4 to 6 (given zeta=sqrt(2)/2 I think.) The process shown could be adapted/modified, I suppose. But I certainly could see how they developed their process. (I'd never asked myself the question you did. But when you asked it, just the asking was sufficient where I could almost immediately see how their mind worked to get there.) Reminds me... question was good. +1 | |

| May 11, 2023 at 17:51 | comment | added | Granger Obliviate | Thank you very much! I was able to follow and understand all the steps. This seems like a neat algorithm for the design of this filters. Most of the time that I have tried to develop the process myself I always end up with some sort of design constraints due to square roots or minus signs that appear and make the values impossible. From your experience do you see any shortcomings of this design or design constraints that might appear. The obvious one for me is that high gain and/or high Q lead to a high value spread for the components. But it never makes the design theoretically impossible. | |
