You just pick the signal at the negative feedback point of the 1-pole lowpass. So you have a multimode 1-pole filter (LP and HP outputs at the same time).rola wrote:Can you show how to make a one pole highpass filter?neotec wrote:Yep, after going through all the stuff again, I finally have got a 24dB resonant highpass filter ... my filter feedback path calculations were faulty^^ralphb wrote:Did you make any headway with the highpass filter?
BTW, I'm not sure about the DFII transposed BL integrator. Isn't the transpose the same as the original (should be)? Or was it about a different thing? (no time to read the whole thread)
