摘要
信号的谐波分析一直是信号处理的基本方法之一。通过对国内外一些提高谐波分析精度的有效方法的研究,从傅里叶算法的基本原理出发,提出了一种新型的谐波分析方法,可以在不增加硬件设备及采样数据的前提下,利用双速率采样的非均匀序列,简单有效地提高谐波分析的精度。计算机仿真证实了该方法的有效性。
Spectra analysis is a basic way of signal analysis. A new spectra analysis way is proposed through investigating some effective ways of improving spectral analysis inside and outside country. The method can improve spectral analysis precision without adding hardware or sampling data with a double-speed sampling nonuniform sequence. Its validity is tested by computer simulation.
