Тема 27. Високоефективни реализации на интерполатори и дециматори с полифазни филтрови структури В Тема 19 беше показано , че всяка цифрова предавателна функция може да се представи в полифазно разложение с различна база М и след това да се реализира с М паралелни клона Реализация на дециматор Ако трябва да се реализира дециматор с коефициент D, можем да реализираме НЧ филтъра по полифазна структура , като изберем базата на разложението М да бъде M = D и така стигаме до следната структура : Ако за всеки от клоновете на тази структура приложим първа каскадната еквивалентност НЧФ f c = f sv /2D D y(m)=w(m) f sy = f sw = f sx /D x ( n ) f sx =1/T x v(n) f sv = f sx Проф .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
