| Abstract: | Take the trapezoidal pulse function as an example,the spectral function of trapezoidal pulse function be solved by using the definition of Fourier transform,the properties of Fourier transform and the convolution theorem.In these three ways,using the properties of Fourier transform and the convolution theorem make the calculation of spectrum function simple and fast,and meanwhile the corresponding physical meaning are more clear as well. |
