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 locally. This estimation  problem can be solved using an identity observer, and the filter  topology falls in this framework. Hence the filter topology represents  a universal building block that can find application in several  problems, such as spectral estimation, time-recursive computation of  transforms, etc. Further, because of the orthogonality constraints  satisfied by the structure, it also represents a robust solution under  finite precision conditions.    The book also presents the observer-based viewpoint of several signal  processing problems, and shows that problems that are typically  treated independently in the literature are in fact linked and can be  cast in a single unified framework. In addition to examining the  theoretical issues, the book describes practical issues related to a  hardware implementation of the building block, in both the digital and  analog domain. On the digital side, issues relating to implementation  using semi-custom chips (FPGA's), and ASIC design are examined. On the  analog side, the design and testing of a fabricated chip, that  functions as a multi-sinusoidal phase-locked-loop, are described.     Feedback-Based Orthogonal Digital Filters serves as an excellent  reference. May be used as a text for advanced courses on the subject.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52634011828497,"sku":"NLS9781461285595","price":126.79,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781461285595.jpg?v=1761866532","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/feedback-based-orthogonal-digital-filters-book-mukund-padmanabhan-9781461285595","provider":"World of Books ","version":"1.0","type":"link"}
