Abstract
An exemplary system and method are disclosed that can detect unobserved and unobservable signals in a subject, or system, using an auxiliary, secondary signal measured from the subject while the unobserved and unobservable signals are known to be present. In particular, the exemplary system and method can used to measure observed signals, e.g., in a nonlinear time-variant system (NLTV system) such as the brain, to measure the unobserved or unobservable signal of interest via response coupling that employs a test instrument configured to facilitate interactions between the primary and the auxiliary signal.
