Synthesis of Regular Digital Filters with Specified Time Characteristics

Abstract

Offered a new conception of digital regular design, which time and frequency characteristics are satisfied the specification, but realization is more simple, compare with standard procedures. Chose basic cascade connection of unified biquades. Usually no more then eight constants should be stored in memory. The program realizations as well as hardware realization of regular filters are more simple then traditional. Biquades coefficients are found by local optimization. In publication is shown DLPF 10th and 14th order design examples, which characteristics are comparing with characteristics of Chebyshev filters with same order and same requirements to control frequency. Ill. 10, bibl. 6 (in English, summaries in English, Russian and Lithuanian).
