Most embedded engineers writing firmware have used some sort of digital filters to clean up data coming from various inputs such as ADCs, sensors with digital outputs, other processors, etc. Many ...

It appears that no particular approximate [nonlinear] filter is consistently better than any other, though . . . any nonlinear filter is better than a strictly linear one. 1 The Kalman filter is a ...

A useful class of nonlinear digital filters exhibits the property of scale invariance. If {x (k)} and {y (k)} represent the filter's input and output sequences, respectively, the output of a ...

As a follow-on course to "Linear Kalman Filter Deep Dive", this course derives the steps of the extended Kalman filter and the sigma-point Kalman filter for estimating the state of nonlinear dynamic ...

This is a preview. Log in through your library . Abstract All conventional control charts can be viewed as charting the output of a linear filter applied to the process data. In this paper, we present ...
