The observations on self-similarity presented provide valuable clues to tackling the inverse problem of synthesis of phase filters. Self-similarity is observed in the far-field diffraction patterns of the corresponding self-similar filters.\u003c\/p\u003e Walsh functions form a closed set of orthogonal functions over a prespecified interval, each function taking merely one constant value (either +1 or -1) in each of a finite number of subintervals into which the entire interval is divided. The order of a Walsh function is equal to the number of zero crossings within the interval. Walsh functions are extensively used in communication theory and microwave engineering, as well as in the field of digital signal processing. Walsh filters, derived from the Walsh functions, have opened up new vistas. They take on values, either 0 or π phase, corresponding to +1 or -1 of the Walsh function value.\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Lakshminarayan Hazra,Pubali Mukherjee\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9811028087\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789811028083\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Springer\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/22\/2017\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 82\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.32lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.21h x 6.14w x 0.19d","brand":"Lakshminarayan Hazra","offers":[{"title":"Paperback","offer_id":47424662470911,"sku":"9789811028083","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_d40a75af-f184-465a-b9f1-72e691a814a2.jpg?v=1761531713","url":"https:\/\/www.whiterainbookhouse.com\/products\/self-similarity-in-walsh-functions-and-lakshminarayan-hazra-9789811028083","provider":"WR Book House","version":"1.0","type":"link"}
