This paper illustrates how pole-zero phase maps can help students to determine the phase of a transfer function from a plot of the poles and zeros. This visualization of the phase of L(s) helps students develop s-plane intuition and facilitates the introduction of the analytical tools of classical control, such as Bode plots, Nyquist diagrams, and Evans root-locus plots.
