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。()

快速转换的矢量/数字字符串的日期。可选的输入令牌/ s的字符串中的日期/时间控制：多个输入令牌可以用来创建多个输出字符串。 令牌提供使用ISO 8601的风格的日期，或单一的日期值。(The rapid conversion of the vector/digital string date. Optional input token/s string date/time control: a plurality of input tokens can be used to create multiple output string. The token is provided using a ISO 8601style date, or a single date value.)
