一种周期信号测量中的自适应抽样算法

An Adaptive Sampling Algorithm for Periodic Signal Measurement

本文提出了一种对周期信号采集的自适应抽样算法，对该算法的实现原理作了详细的分析，并将它与未改进的算法作了比较同时还将该算法用于交流信号谐波的DFT分析，其结果表明频谱泄漏大大小于未改进的抽样算法。

An adaptive sampling algorithm for periodic signal measurement is prasented. The development of the new algorithm is analyzed in detail,and compared with the general approach. To illustrate the practical applicability of the propalgorithm, foe paper shows how the proposed method canbe used in the case of DFT analysis of harmonic signals. Results show that the new algorithm is capable of reducing the leakage effect in DFT analysis.
