Thus, the zeros of the function are at the point Assume the cutoff frequency is equal to 1, the poles of the filter are the zeros of the gains denominator The poles of the gain of type II filter are the opposite of the poles of the type I Chebyshev filter. However, since the a and b coefficients are real numbers, the complex poles (or zeros) must occur in conjugate pairs. Webpoles and zeros calculator The main additions are input fields for precision pole-zero placement, and an option to display the response with a log frequency scale. The plot shows that all poles of CL1 are in the left half-plane, and therefore CL1 is stable. If both fast responses and good static accuracy are desired, a lag-lead compensator may be employed. To find the zeros of the function it is necessary and sufficient to solve the equation : The zeros of the function will be the roots of this equation.
