用DFT近似计算连续时间周期信号的频谱，对matlab新手适用。(Approximate calculation using DFT spectrum of continuous-time periodic signal of matlab novice apply.)

已实现了MATLAB下的音频AGC，效果还可以，做起来才发觉比较简单，关键是要有高效的算法。如果能在实现AGC的同时做到噪音消除和回音消除，则效果更佳。(MATLAB has been achieved under the audio AGC, the effect can be done only to find relatively simple, the key is to have efficient algorithms. If you can do while in the realization of the AGC noise cancellation and echo cancellation, the better.)
