Description: In mathematics, the discrete-time Fourier transform (DTFT) is one of the specific forms of Fourier analysis. As such, it transforms one function into another, which is called the frequency domain representation, or simply the "DTFT", of the original function (which is often a function in the time-domain).-This file includes matlab source code about DTFT and also includes explanation report

Description: 试求的DTFT，并画出其模、相角、实部和虚部图。
实验要点：的DTFT为：，因此根据该表达式用MATLAB编程。是上取值的实变量，是复值函数，且具有周期性和对称性。图形显示时可以只考虑区间上的分布，通常还把横轴对做归一化处理。
要求：分析参考程序，写实验报告，说明编程思路。掌握有关函数abs、angle、real、imag的用法，以及有关点除运算。掌握有关绘图函数的使用。-DTFT matlab signal
