The Universality of the Kalman Filter [PDF]
, 2021 The universality of the Kalman filtering can be found in the control theory. The Kalman filter has found its applications in sophisticated autonomous systems and smart products, which are attributed to its realization in a single complex chip. In this chapter, considering the Kalman filter from the perspective of conditional characteristic function ...

Universal Filtering Via Hidden Markov Modeling [PDF]
IEEE Transactions on Information Theory, 2008 The problem of discrete universal filtering, in which the components of a discrete signal emitted by an unknown source and corrupted by a known DMC are to be causally estimated, is considered. A family of filters are derived, and are shown to be universally asymptotically optimal in the sense of achieving the optimum filtering performance when the ...

Universal current‐mode filters and parasitic impedance effects on the filter performances
International Journal of Circuit Theory and Applications, 2007 AbstractIn this letter, two universal current‐mode (CM) filters for simultaneously realizing low‐pass, band‐pass and high‐pass characteristics are proposed. Both of the presented filters can also realize notch and all‐pass responses with interconnection of the relevant output currents. They employ second‐generation current‐controlled conveyors (CCCIIs)
