So, poles push the frequency response up around their corresponding frequency, and zeros pull down around theirs. While I was at it, I improved the log tick value scaling. Yes, the pole would determine the 3 dB point for a lowpass, assuming the zero wasnt close. However, since the a and b coefficients are real numbers, the complex poles (or zeros) must occur in conjugate pairs. Determination: Poles are determined by equating D (s) with 0 and solving for s. Zeros are determined by Since the both pole/zero pair are equal-distance to the origin, the gain at zero frequency is exactly one. The zeros of the function will be the roots of this equation.

Another thing is that it lets you take a picture of the problem for it to solve (works most of time but can bug out, dont rely on it). How do you find the roots of a polynomial. Ive thought many times about some of these features, and as you noted, one leads to another, and the only sound solution would be to go into the business of a making a commercial filter design software package, and Id be heading far off track from what Im trying to do, The phase plot is the most obvious, but in the end weve got a second order filter, for which you can look up the unexciting phase characteristics elsewhere, and they are simply an accepted byproduct of this type of filter. Remember that for the poles to move off the horizontal axis, they have to be a conjugate In that case the signs are wrong, or rather, inconsistent with how you write the direct forms.
