代码说明:

说明:  在共梯度法中 只有当初值的选取靠近最优解时 迭代才会收敛 当远离时发散 且 当精度控制为0.1时可以实现 但设为0.01时就实现不了(numubrical)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    先对语音信号进行采集、播放,分析其频谱,对该信号源添加噪声,再播放音频并分析频谱,然后分别通过IIR低通、带通滤波器和FIR低通、带通滤波器,分别播放音频和得到滤波后的频谱。(Firstly, voice signal acquisition, play, analyze its spectrum to add noise to the signal source, and then play the audio spectrum analysis, and then were by IIR low-pass, band-pass filter and FIR low-pass, band-pass filters, respectively, play audio and get the spectrum after filtering.)
