摘要
分析比较了现有的一些基于DFT类谐波分析及频率测量算法,给出一类准周期信号的时域模型,提出一种基于窗口DFT的准周期信号频率精确算法,并对算法进行仿真。
In this paper the analysis and comparison of some existing algorithms based on DFT for the harmonic analysis are made a model for kinds of quasi-periodic signal in time domain is given and based on this an exact interpolation algorithm based on DFT with window for the quasi-periodic signal and its simulations are presented.
