MFC详细的学习例子，很多实例供初学者学习(MFC detailed study examples, many examples for beginners to learn)

filter audio signalThen use the Butter function, for instance to obtain your signal(type Butter in your Matlab command window and you will find many other type of filters). Once you have obtained the B and A vector coefficients you can filter your signal using the function filter. y=filter(x,A,B) x(is your input signal) and y your filtered signal.(an example filtering signalThen use the Butter function, for instance to obtain your signal(type Butter in your Matlab command window and you will find many other type of filters).
