Study on the Application of Mathematic Analytical Methods in Signal Distortion Measurement by Digitizing Means

摘要：

The purpose of the study is to meet the needs of signal distortion measurement by digitizing means nowadays. To insure the test accuracy of the signal distortion, the spectrum analysis algorithm and the regression analysis algorithm and their application are researched. By means of the emulation and analysis, it is found that each algorithm has its faults in signal distortion test work. Through further analysis about the tested signals characteristic and the algorithms applicability, it is found that the error trends of these two algorithms are different ,and the intersecting point is discovered. The result showed that the different algorithm should be chose to use in connection with the distorting degree of the tested signal.
