| Abstract(in English) | A new method to design tunable band-pass and band-stop IIR digital filters with higher accuracy of tuning is proposed in this paper. It is based on cascade realization and spectral transformations connected to proper development or selection and design of prototype sections (first and second-order low-pass and high-pass sections and first-order all-pass sections) with minimized sensitivity and canonic number of multipliers. Applying the method, new tunable second- and fourth-order band-pass/band-stop sections with independent tuning of the center frequency and bandwidth and with higher universality are developed and many more may be obtained for different frequency ranges. It is shown that they have much better accuracy of tuning and lower noises compared to all other known similar sections. They permit also implementations with much shorter coefficient word-length, decreasing thus the volume of the computations for coefficient updating and simplifying the adaptive filter applications. |
