This paper was written in 1996 and appeared in the Medical Electronic Magazine. The intent of the paper is to show how simple digital filters are and to show how easy it is to implement FIR
filters. If you can recall anything you learned about Fourier Transforms, then you can implement an FIR filter.
This paper has been the most downloaded item from our web page since that time. Hence it has earned it's place as the first paper to be posted into our Technical Library.
PID loops while widely used, do have limitations in achieving highest possible bandwidth. This paper explores those limits and determines the effect of extraneous poles, loop delays and such.
