重点将是“我如何创建这样一个取决于输入周期和滤波器采样频率‘Fs’的‘可变 FIFO 缓冲区’？
如果有人对这样的问题有任何想法或想法，那么我将很高兴知道，这将对我在这里的项目有很大帮助。

Maybe I don't fully understand what it is you're looking for here but I think you already have all the information that you need.
Fs = 1000; %% or whatever your sampling rate is to begin with.
Order = 3; %% Or whatever order you decide to work with.
Buffer_length = (Order/2)*Fs; % this will be the amount of data in each buffer
If you're looking for someone to give you anything more than this you're going to have to provide additional information and show what you're tried to do so far.
