DESIGN PHILOSOPHY Design by analysis in the frequency domain using Nyquist techniques is performed in the same general manner as all other design methods in this book: appropriate compensation networks are introduced in the forward or feedback paths and the behavior of the resulting system is critically analyzed and reanalyzed. In this manner, the Polar Plot is shaped and reshaped until performance specifications are met. The procedure is greatly facilitated when computer programs for generating Polar Plots are used. Since the Polar Plot is a graph of the open-loop frequency response function GH(
