Of Course it is. You must evaluate the transfer
function of the filter in the unit circle.

hi pd-list!
i have recently tried to build some filters using cpole and czero, not
completely unsuccessfull (at least the lowpass sounds somewhat like a
lowpass...), but i have a problem calculating the right gain (or
attenuation) factor. for the lp it seems to work more or less (ok
