说明：  观察数据长度N的变化对DTFT分辨率的影响 这几个程序是老师写的 对于理解DTFT有很大帮助(Effect of observation data length N on DTFT resolution These programs are written by the teacher and are very helpful for understanding DTFT.)

使用每秒10个采样的频率 ，对信号 进行采样，画出原始信号的傅立叶变换X(f) 和理想采样信号的傅立叶变换 。假定重构滤波器是带宽为 的理想低通滤波器，具有带通增益 ，画出重构滤波器的输出(Using 10 samples per second frequency, the signal is sampled, to draw the original signal Fourier transform X (f) and the ideal sampling signal Fourier transform. Reconstruction filter is assumed that the ideal bandwidth low-pass filter with a bandpass gain, draw the output of reconstruction filter)
