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. The Bode plots of the example three low pass filters: A high-pass filter decreases the magnitude of low frequency components. A lag compensator decreases the bandwidth/speed of response: good to reduce the impact of high-frequency noise, bad if you want the system to react fast -> use lead compensator. The Z-Transform is a tool that provides a method to characterize signals and discrete-time systems by means of poles and zeros in the Z domain. Web. The plot shows that all poles of CL1 are in the left half-plane, and therefore CL1 is stable. Our online calculator, based on Wolfram Alpha system is able to find zeros of almost any, even very complicated function. In your other material you write y[n] = . The plot below shows the poles (marked as "x") and the zeros (marked as "o") of the The gain, k, is not shown. The pole/zero plot of the example lead-lag compensator: See the PI Controller : THEORY + DEMO article for more details. As you have guessed correctly, zeros come from numerator.
