Define the numerator and denominator coefficients for the rational transfer function, b = [2,3]; a = [1,0.2]; Filter the subsequences x1 and x2 one at a time. Output the final conditions from filtering x1 to store the internal status of the filter at the end of the first segment. ...
In MATLAB, you can obtain the impulse response of a Finite Impulse Response (FIR) filter using the filter function or the impz function. Here, I'll provide you with an example using the impz function. Let's assume you have the coefficients of your FIR filter stored in a vector called h...
Filters are data processing techniques that can smooth out high-frequency fluctuations in data or remove periodic trends of a specific frequency from data. In MATLAB®, thefilterfunction filters a vector of dataxaccording to the following difference equation, which describes a tapped delay-line fil...

Kalman Filter在Matlab的简单应用实现 经过卡尔曼滤波器的数学推导和证明以后,我们就可以在Matlab里利用几个简单的例子实现它,通过代码来加深理解。 现假设有一房间,根据以往经验判断温度在25℃左右。我们定时测量房间温度,可以想象,在我们测量温度时外界的天气变化、空气流动等等,会给房间这个系统带来过程噪音W(k),假设...
