摘要:通过分析连续周期方波信号的傅里叶级数和傅里叶变换的关系,为谐波分析提供理论依据,针对目前谐波分析存在的运算量大、计算时间长.实时性差等技术瓶颈,采用MATLAB仿真,用信号发生器和示波器模拟谐波叠加过程,通过FFT(快速傅里叶变换)对信号频谱进行分析。
Abstract: By analyzing the relationship between Fourier series and Fourier transform of continuous periodic square wave signal, theoretical basis is provided for harmonic analysis. In view of the curent technical bottlenecks of harmonic analysis, such as large amount ofcalculation,long calculation time and poor real -time performance，MATLAB simulation is adopted, and the pocess of harmonicsuperposition is simulated with a signal generator and osilloscope. The signal spectrum is analyzed through FFT (Fast Fourier transform)
