Abstract
The invention relates to an arrangement for measuring and assessing properties of a system () which transfers an electrical, mechanical or acoustical signal or converts an excitation signal x into another signal y. An error system () models the transfer behavior of the system, estimates a desired output signal y', and generates an error signal e which reveals the excess distortion and disturbances of the output signal y at any time instant t, and can reveal peak values of transient distortion having low power which might otherwise be masked by noise and regular distortion. The error signal is supplied to an assessment system (), where convenient distortion measures are calculated and the distortion is displayed versus properties of the signal (e.g., instantaneous frequency and amplitude). The assessment system may also generate a control output () to modify signal x to ensure an optimal excitation of the system.
