Most measuring methods by using digital signal processing technique developed recently are only for measurements in a linear range. There is still no suitable measuring method by a digital processing system for measurement of nonlinear distortion of acoustical devices. An accurate and convenient nonlinear distortion measurement system should be developed. The authors already proposed a new digital distortion measuring method for acoustical devices briefly. This method applies a Pink-TSP signal (Time Stretched Pulse, i.e. quickly swept sinusoidal signal), whose frequency band is partially eliminated, to an acoustical system to be measured. The detected component produced in the rejected band is measured as a distortion. This paper analyzes experimental results theoretically by using a single resonant system.
