WebFigure 1: The pole-zero plot for a typical third-order system with one real pole and a complex conjugate pole pair, and a single real zero. 1.1 The Pole-Zero Plot A system is characterized by its poles and zeros in the sense that they allow reconstruction of the input/output differential equation. WebRational Zero Theorem. If a polynomial function, written in descending order of the exponents, has integer coefficients, then any rational zero must be of the form ± p / q, where p is a factor of the constant term and q is a factor of the leading coefficient.
