fp=2400hz,fs=5000hz,rp=3db,rs=25db.求其3dB时的各项参数！(fp = 2400hz, fs = 5000hz, rp = 3db, rs = 25db. for its 3dB at the time of the parameters!)

在MATLAB环境下使用谱减法对语音信号进行增强，程序可以运行(In the MATLAB environment using spectral subtraction speech signal enhancement program can run)

Angle among 3 points

有关DFA和MF-DFA的一些代码，只要你能仔细阅读的话相信总有一个适合您(Some code about DFA and MF-DFA, as long as you can read carefully, then I believe there is always a right for you)

产生不同频率、不同幅度的两种正弦波信号 对两个信号进行叠加并做频谱分析 还原原来两个信号（LPF)(Produce different frequency, the two sine wave signals of different magnitudes of the two signals are superimposed and do spectral analysis to restore the original two signals (LPF))
