正在学数字信号处理,感觉上学期信号与系统学得不扎实，因为当时只是死记公式，这学期数信老师提倡动手实践，觉得自己在编程中对公式理解得更加深刻了。 以下是我写的FFT，欢迎指教。-is studying digital signal processing, signal feel semester with enough solid school system, because only memorizing formulas, a few letters this semester to promote hands-teachers find themselves in the right programming formula to understand more deeply. The following is what I wrote FFT welcome to enlighten.
