A method is provided for analyzing stability and passivity of physical systems. A physical system having time delays is represented as a linear circuit model. The linear circuit model is transformed into a corresponding transform domain circuit model. Sensitivity analysis is applied to the transform domain circuit model for generating information indicative of the stability or the passivity of the physical system having the time delays. A graphical representation may be created of the information indicative of the stability or passivity of the physical system having the time delays.
