Follow-up Comment #1, bug #47302 (project octave): I think your way of thinking is correct. Unfortunately octave control tool box does not handle delays very well. If you just keep them as polynomials and do the math your self then filter still will work. I had to do this for myself last week. use conv( p1,p2) to multiply 2 polynomials and p1+p2 to add them. and deconv(p1,p2) to divide p1 by p2 HTH _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?47302> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
