AB  - A new approach for measuring distortion provides a continuous distortion curve versus frequency, and the method is suitable for use with noise, music, and multitone stimuli. Distortion measures are derived from dual-channel analysis of the noncoherence between the stimulus and the response. The mathematics is based on Volterra theory, which is an extension of linear system theory but applied to nonlinear systems. Because the technique uses standard signal processing, the approach is simple, accurate, and repeatable.
