| 摘 要： | 准同步技术是在同步采样技术基础上发展起来的技术，其采样周期不要求与信号周期严格同步。文中采用先对周期信号作准同步采样，然后再结合DFT算法对周期电信号进行谐波分析与测量的方法，仿真结果表明，该方法具有较高的准确度。

| Abstract: | A technology of quasisynchronous sampling is introduced in this paper,which is based on the technology of synchronous sampling.It dosen't need strict synchronous sampling and can gains high accurate results.This paper proposes the process of the periodic function by using the technology of quasisynchronous sampling and DFT algorithm.The results of computer simulation confirm the accuracy of the approach. |
