In statistics, the Kalman filter is a mathematical method named after Rudolf E. Kalman. Its purpose is to use measurements that are observed over time that contain noise (random variations) and other inaccuracies, and produce values that tend to be c

用matlab模拟的kalman的低通滤波器,附带代码说明
某系统接收端接收到的信号为
y=4*cos(2*pi*310*t)+2*sin(2*pi*40*t)
(G) 发现此信号夹杂了一个正弦噪声noise= 4*cos(2*pi*310*t),
请设计一个带阻滤波器将此噪声滤除,从而恢复原信号。
要求:
(1)请写出具体的MATLAB程序,并详细解释每条程序
(2)画出滤波前后信号的频谱图
(3)画出所设计滤波器的幅频和相频特性图,并写
