Description: 应用傅里叶变换DFT,分析各种离散信号x(k)的频谱。离散周期信号可以展开成傅里叶级数,所以离散周期信号的频谱 是一个周期的周期性离散频谱,各谱线之间的间隔为 ,而且存在着谐波的关系。 -DFT application of the Fourier transform, analyze discrete signal x (k) of the spectrum. Discrete signal cycle can begin as Fourier series, the discrete signal spectrum is a cyclical cycle of discrete spectrum, the line between the interval, but there is a harmonic relationship.

Description: 信号与系统试验报告
离散傅立叶变换(DFT)和频谱分析
一、实验内容
1、实验题目
(1)编写DFT、IDFT程序,并验证其正确性(提示:可利用冲激函数进行验证)。
(2)计算信号f(t)=e-at2sin(2∏ft)的离散傅立叶变换(DFT),求其振幅谱,相位谱、振幅最大值对应的频谱(检测主频)以及对发f(t)进行DFT变换的结果实现IDFT变换,并画出图形。
参数选择如下:频率f =30HZ,a=f 2㏑(M),M=2.5
2、通过实验理解信号振幅谱、相位谱的物理意义,掌握DFT、IDFT算法的实现方法。
