摘要
介绍了周期信号频谱分析的方法,指出教科书中的错误,并且结合信号的单目运算,分析了信号频谱的变换规律,提出周期信号频谱信息的快速计算方法。实例展示了应用此方法可以快速计算周期信号的频谱,效果良好。
This paper introduced the method of frequency spectrum analysis of periodic signal, and pointed out a mistake in the textbook. Based on the monocular operation of signal, analyzed the rule of spectrum transform and proposed a new fast method for frequency spectrum analysis of periodic signal. Ex amples showed that this method can be used to calculate frequency spectrum of periodic signal.
