此程序为测试窗函数宽度对时－频分辨率的影响，即测不准原理，对时间分辨率和频率分辨率只能取一个折中，一个提高了，另一个就必然要降低，反之亦然。-This procedure for the test window function width on- frequency resolution, that is, the uncertainty principle, the time resolution and frequency resolution can only take a compromise, an elevated, and the other is bound to reduce, and vice versa .
