Muhammad Amir Yousaf . Frequency Response of R,L,C. How varying frequency affects the opposition offered by R,L and C. Frequency response concepts and techniques play an important role in control system design and analysis. . Closed-Loop Behavior. In general, a feedback control system should satisfy the following design objectives:. Bode Plots Page 1 A Bode plot is a standard format for plotting frequency response of LTI systems.
