【摘要】 本文提出一种付里叶变换的压缩算法ＣＦＴ（ＣｏｍｐａｃｔＦｏｕｒｉｅｒＴｒａｎｓｆｏｒｍ），它比传统的ＦＦＴ算法更为快捷和灵活．本文从数学上证明了ＣＦＴ算法的正确性，并用作者编制的ＣＦＴ程序和ＦＦＴ程序进行了实例计算及比较，同时讨论了ＣＦＴ在电网谐波分析中的应用．更多还原

【Abstract】 This paper proposes a Compact Fourier Transform(CFT) method which is faSter and more flexible than the conventional Fast Fourier Transform(FFT) method.It also proves in mathematics that CFT method is perfect.The case calculation and comparison between the conventional FFT program and CFT made by the author in C language are conducted and the application of CFT method to harmonic waves analysis of electric power systems is discussed.更多还原
