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:neotec wrote:ralphb wrote:Did you make any headway with the highpass filter?
Yep, after going through all the stuff again, I finally have got a 24dB resonant highpass filter ... my filter feedback path calculations were faulty^^
Can you show how to make a one pole 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)
