摘要
傅里叶级数变换是数学物理方法常用的一种变换方法,它在大学物理中运用十分广泛,尤其是电流信号处理中。从高等数学中傅里叶变换的定义出发,对电流信号中常见方形信号、锯齿信号进行傅里叶变换,得出结论,复杂电流信号都能分解成许多一系列简谐电流信号的叠加。
Fourier transform is a common transformation method used in mathematical physics methods. It is widely used in university physics, especially in current signal processing. Based on the definition of Fourier transform in higher mathematics, Fourier transform is performed on the square signal and zigzag signal in current signals, and it is concluded that complex current signal can be decomposed into the superposition of many simple harmonic signals.
