WitrynaInstead of shifting the data every time step through an array we use a ring buffer and just change the start of the ring buffer with a pointer. WitrynaTable 15-1 shows a program to implement the moving average filter. Noise Reduction vs. Step Response Many scientists and engineers feel guilty about using the moving average filter. Because it is so very simple, the moving average filter is often the first thing tried when faced with a problem. Even if the problem is completely solved,
