【摘要】 从数字信号处理的基本原理出发,给出了谐波泄漏产生的根本原因,指出实际工作中的傅立叶分析都是对非均匀采样序列进行的;如果能有效地逼近理想整周期采样序列,即使是非均匀采样,也可以提高谐波分析的精度.计算机仿真结果证实了这种分析的正确性.更多还原

【Abstract】 This paper analyses the fundamental cause of the spectrum leakage based on the theory of digital signal processing,and points out that an actual DFT analysis is completed with a heterogeneous sampling sequence.If the ideal sequence of synchronous sampling can be realized effectively,the accuracy of spectrum analyses can be greatly improved.The validity of the method is verified by computer simulation.更多还原
