There are plenty of resources available to help you clear up any problems you may have. Now, it would be very helpful as you add some of the other things you mentionedmore poles and zeros, all pass filterthen youre back in the business of making a filter design package. Poles determine the transient response of the system, while the zero determines the speed of response to be more general. Zeros become important when there are delays, or non-minimum phase. Cite Mathematics is the study of numbers, shapes, and patterns. I found a very nice web app showing interactive filter design with direct visualization in frequency domain and z-domain ( poles and zeros ) : But Im not going to edit articles going back to 2003, so yes, a in the numerator here , How do you calculate the coefficients from the poles to get the frequency response? However, since the a and b coefficients are real numbers, the complex poles (or zeros) must occur in conjugate pairs. Introduction to Zeros & Poles of a Transfer Function.2. The Z Transform, X (z), is the equivalent of the Laplace Transform for discrete time. The Bode plots of the example three high-pass filters: Notch filter could in theory be realized with two zeros placed at +/-(j omega_0). Looking for a little help with your homework?
