Feedback-Based Orthogonal Digital Filters: Theory, Applications, and Implementation

Feedback—Based Orthogonal Digital Filters: Theory, Applications, and Implementation develops the theory of a feedback—based orthogonal digital filter and examines several applications where the filter topology leads to a simple and efficient solution. The development of the filter structure is linked to concepts in observer theory. Several signal processing problems can be represented as estimation problems, where a parametric representation of the input is used, to try and replicate it loc...
