Aa. Shatalov et Ab. Yastrebkov, DIGITAL SIGNAL FILTERING ALGORITHMS OPERATING OVER LONG-TERM INTERVALS, Telecommunications & radio engineering, 47(11), 1992, pp. 97-102
Different versions of digital signal filtering in the time and frequen
cy domains employing a fast Fourier transformation (FFT) and number-th
eoretic transformations (NTT) are examined. Results of a comparative a
nalysis of possible digital filter realizations based on the number of
arithmetic operations are given.
