Good day, ladies and gentlemens.
Can I arbitrary select topology for each filter stage in FilterPro 3.1.0.23446 and how I do this? F.e. Sallen-Key for first stage and MFB for second stage of 4-th order LPF.
Thank you for advise.
No, I'm afraid you can't select circuit topology by stage in FilterPro. This is something we plan to enable in a future active filter design tool.
