Abstrakty

PL

W artykule przedstawiono metodę projektowania minimalnofazowych filtrów FIR o rzadkiej odpowiedzi impulsowej. Przestawione rozwiązanie wykorzystuje filtr interpolacyjny i jest przeznaczone do projektowania filtrów wąskopasmowych. Pokazano, że liczba niezerowych współczynników filtru zaprojektowanego zaproponowaną metodą jest mniejsza niż dla filtrów projektowanych metodami znanymi z literatury przy zachowaniu tych samych parametrów charakterystyki amplitudowej.

In the paper a method for minimum-phase, sparse impulse response FIR filter design was presented. The proposed solution uses an interpolation filter and is dedicated for narrowband filters. It was demonstrated, that the number of non-zero coefficients of the filter designed by the proposed method is smaller than the number of coefficients obtained by other methods, with preserved magnitude frequency response of the filter.
