Unknown Filter Type - larkjon - Jan 13 17:46:00 2005

Hi, I may have inadvertly posted this twice. If so, I apologize. I've "inherited" the following filter: Yn = Yn-1 + C(Xn-Xn-1)^2 - C(Xn-Xn-1)(Yn-1) Where Yi are outputs Xi are inputs C is a constant The filter performs a smoothing function. Does anyone recognize the form of this filter? What type is it? Any good reference material on this filter? Thanks, Jon |

Hi Jon I may be wrong: It looks like it is a discrete time version of a system governed by the following equation: dy(t)/dx = C[(dx(t)/dt) - y(t) ], where x(t) and y(t) are functions dependent on time and a derivative of y wrt x exists. Again, I am stressing that I may be wrong.
