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。
