用MUSIC算法作谐波恢复，该算法精确度非常高，能够分辨0.013Hz的频率分量。(Using MUSIC algorithm for harmonic retrieval, the algorithm accuracy is very high, to distinguish the frequency components 0.013Hz.)

语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)
