cat-20-c-1(huge improvement in flight program

@littlephysicscat you are a bright pupil

@TritonAerospace by the way,I'm a Chinese high school student,so I'm sorry i can't provide reference in English.

: ( excuse my poor English

@TritonAerospace usually we use Fourier transform to convert a signal into frequency domain and process it,then inverse transform it back into time domain.but if your process in F domain is just multiplying a function of frequency,we can simplify it, as we know multiplication in the frequency domain is convolution in the time domain. so that the program will run faster .That's why i write the flight program like this.

@TritonAerospace Discrete convolution is a mathematical operation that takes two discrete functions and produces a third discrete function.it's a discrete version of integral transformation.It is used in signal processing and digital image processing to modify or extract features from signals and images. it can be considered as an extension of "moving average".

@littlephysicscat also what do you mean by discrete convolution of length 5?

i am very interested in this.
where can i find reference documents to make something like this?

有飞控程序的静不稳定飞机。
飞控程序由三部分组成：攻角补偿，角速度保护，自动配平。配平使用了简易的滤波器（长度为5的离散卷积），用于避免自激振动。（这是我觉得最有技术的地方捏）
