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，并写出具体参数-Low-pass filter with kalman matlab simulation, with code shows the signal received by the receiving end of a system y = 4* cos (2* pi* 310* t)+2* sin (2* pi* 40* t ) (G) was found in this sinusoidal noise signal is mixed with a noise = 4* cos (2* pi* 310* t), Please design a bandstop filter to filter this noise, thereby restoring the original signal. Requirements: (1) Please write specific MATLAB program, and explain in detail each program (2) Draw the spectrum before and after filtering the signal (3) filter is designed to draw the amplitude and phase frequency characteristics map and write specific parameters
