| Abstract(in English) | There is still no suitable measuring method by a digital processing system for nonlinear distortion of acoustical devices. The authors present a new amplitude nonlinearity measurement by using Pink-TSP (time stretched pulse) signal. This method applies a Pink-TSP signal, whose frequency band is partially eliminated, to the device. The detected component produced in the rejected band is measured as a distortion. This paper analyzes effect of parameters of the Pink-TSP signal and the band-eliminated TSP. Then, design paradigm of distortion measurement system with a practically allowable error is examined. |
