Abstract :
A new time-domain interpretation of H.W. Bode´s (1945) integral is presented. This allows for a generalization to the class of time-varying systems which possess an exponential dichotomy. It is shown that the sensitivity function is constrained, on average, by the spectral values in the dichotomy spectrum of the unstable component of the open-loop dynamics
