Thank you so much for your answer, Joe and Alexandre.
You're right, Joe. I was actually referring to hip~ when talking about the
impulse response, indeed hip~ is one-pole and one-zero. It might be good to
specify it in the help file.
What formula would you use for the coefficients of rpole~ and rzero~ to
