| 摘 要： | 主要讨论了测量失真度的准同步方法——采样周期不要求与信号周期严格同步。该方法用于失真度测量，有效地克服了传统的基于DFT的失真度测量方法中非整周期采样引起的频谱泄漏对测量结果的影响，实验结果表明，该方法的采用使失真度测量的准确度提高了一个数量级。

| Abstract: | The quasi-synchronous technique, which means that sampling period doesn't synchronize with signal period strictly, is discussed. Compared with traditional signal distortion measurement based on DFT, the technique can effectively minimize the spectrum leakage caused by non-integer-period sampling. It has been proved by experiment that accuracy of distortion measurement can be improved by 10 times. |
