频率估计 1）产生一个单频实信号，加上一定信噪比的噪声。 2）对含噪声的信号进行频率估计。估计方法可以查阅相关文献。 3）统计估计出来的频率和真实频率之间的误差。 4）验证该频率估计算法在不同信噪比、不同数据长度下、不同频率时候的性能。 (Frequency estimation 1) produce a single-frequency real signal, plus a certain SNR noise. 2) noisy signal frequency estimates. Estimation method can access relevant literature. 3) out of the statistical estimation and frequency error between the true frequency. 4) Verify that the frequency estimation algorithm under different SNR, different data length, when the frequency of different properties.)

最标准的有源电力滤波器仿真模板，是本人在毕业论文设计当中自己绘制的，偶很高的参考价值(active power filter)

能量重心校正法，进行频谱的幅值修正，算法可以参见谢明、丁康老师的频谱分析文章。(Energy center of gravity correction method, the amplitude correction of the spectrum, spectrum analysis of the algorithm can be found in Xie Ming, DING Kang teacher article.)
