In electrical engineering and control theory, a Bode plot /ˈboʊdi/ is a graph of the frequency response of a system. It is usually a combination of a Bode magnitude plot, expressing the magnitude (usually in decibels) of the frequency response, and a Bode phase plot, expressing the phase shift. As originally conceived by Hendrik Wade Bode in the 1930s, the plot is an asy… 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.
