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 withou

对语音信号进行滤波，得到清晰度提高的信号。通带频率600Hz；截止频率Fc为1200Hz；通带衰减为1dB，阻带衰减为30dB。使用的窗函数类型为Hanning 窗。-design of fir filter,get the original voice without noise
