摘要
谐波理论分析对于非正弦交流电路的研究具有重要的理论和实际意义。本文首先介绍了谐波的概念，其次从理论上对谐波进行了分析并给出了谐波的分析方法——傅立叶级数法，再次以实际电路为例，详细分析与论证了它的应用，具有一定的应用价值。
The analysis of modulation wave theory has very important theoretical and actual meaning for studying non sine alternating current. This article first introduces the concept of the modulation wave,then theoretically analyses the modulation wave and provides the analytical method——Fourier progression analytical method,finally takes real circuit as an example to analyse and demonstrate its application in details. It also has certain application val-
