Description

ABSTRACT:
A method and apparatus for estimating transfer functions among multiple physiologic or biologic signals in the presence of feedback. The invention comprises the injection of broad band purturbation into one or more of the subsystems under study, and measuring signals from the subsystems. These signals are transformed to generate a new set of n signals. Casual transfer functions between the signals and additive noise sources are used to represent the relationships between the n signals. Parametric system identification techniques are then used to characterize quantitatively at least two casual transfer functions and noise sources. This method and apparatus provides a powerful tool with which to characterize the interactions of subsystems in the presence of feedback.
