There is still no suitable measuring method by a digital processing system for nonlinear distortion of acoustical devices. This paper presents a new amplitude nonlinearity measurement by using Pink-TSP (time stretched pulse) signal. This method applies a TSP signal, whose frequency band is eliminated partially, to the device. The detected component produced in the rejected band is measured as a distortion.
