This thesis introduces a digital method which can generate standard distortion signal. Based on the mathematical definition of distortion, standard distortion signals with fixed distortion are generated by Matlab, and then downloaded to the function signal generator. At last the standard signal distortion is output by the function signal generator. In addition, this paper introduces the realization of the distortion measurement calibration system. The method introduced in this thesis is verified successfully with audio analyzer, and the related experimental results are also given to the readers. In order to solve the problem that most of distortion sources are heavy and can not be programmed to control, this method which has broad application prospects uses only one function signal generator can complete to output 0.5% and above arbitrary standard distortion signals. |
