filtergraph~ display question

    Aug 27 2011 | 1:29 am
    Is there a coefficient formula that would cause filtergraph~ to display a one pole, two pole, three pole, etc. lowpass filter response? The onepole~ help file seems to suggest a formula that is equivalent to a one pole filter. I have tried cascading multiple copies of that, and also using highorder, but I can't seem to make it work. Is it even possible with filtergraph? Thanks.
