The characteristics of a linear component are known to be completely determined by its steady state frequency response which relates the output of the component to its input. Hence, the analysis and synthesis of a complex system are simplified when the frequency response of each unit making up the system is known. For such a system, the overall amplitude ratio of output to input for any frequency is obtained by multiplication of the amplitude ratios for each individual component. As a result of this property, a large body of design procedure for control systems has been based on linear frequency methods.
