使用低通滤波器从含有噪声的信号中提取有用的正弦波
(见实验指导书 实验九 数字滤波器中的第一题)
目的:用数字滤波器从含有高频噪声的采样数据中提取正弦信号。
要求:①输入信号为一正弦波,并加入一个白噪声的干扰来模拟信号传输中的随机干扰信号(用以模拟含有噪声采样序列)。
(模拟含有噪声采样序列具体可用正弦波信号叠加高频噪声来实现,为了使滤波效果明显,本实验的高频噪声是用高频均匀分布白噪声(Uniform)通过Butterworth高通滤波器过滤生成的,高通滤波器的截止频率设为10倍输入信号频率。)
②在程序中设计一个低通巴特沃斯滤波器,以滤除信号中的噪声分量,提取输入的正弦波信号 。
③可调节信号滤波器的截止频率和阶数,可显示滤波前与滤波后的时域信号。
④给出滤波前与滤波后的频谱特性的显示。
