Synthesis of Bandpass Filters with an Arithmetic Symmetric Amplitude-Frequency Characteristic

The relevance of this article reflects the class of filters under study, the basis used (homogeneous links) and the direction of research (ensuring low parametric sensitivity). For practice, the actual problem of synthesis of pole-passing filters (PPF) obtained from the prototype. An effective method for the synthesis of low-sensitivity active filters of various structures is proposed. The following tasks are solved in the work: development of synthesis methods for structural and schematic diagrams of low-sensitivity active filters of arbitrary order; development of methods for the synthesis of band-pass and notch filters with arithmetically symmetric amplitude-frequency characteristics; setting the conditions for the minimum sensitivity of the frequency response of active filters and the development of a method for synthesis of filters with minimum sensitivity; a method for the synthesis of matrices of fractional-rational functions with complex coefficients is proposed.
