V.; Fesich, W. P.A new topology of the second-order low-pass filter containing three operational amplifiers is proposed. As known, a feature of second-order filters based on operational amplifiers is the interdependence of the main filter parameters, such as the pole frequency, Q factor and gain. The second-order filters synthesized by the state variable method have the smallest relationship between the main parameters, but they also do not allow independent adjustment of the gain and Q factor, and contain at least three operational amplifiers. The proposed low-pass filter topology also contains three operational amplifiers and provides the possibility of independent setting of the pole frequency, Q factor and gain, as well as the possibility of independently adjustment of the Q factor and gain. Relationships have been obtained that relate the pole frequency, Q factor and filter gain to the nominal values of the passive filter elements. On the basis of these ratios, the possibility of independently changing the Q factor and gain of the filter is shown. On the basis of this topology, a second-order universal filter was synthesized with the possibility of independent setting and adjustment of the main parameters. A cut-off filter with independent installation and adjustment of the main parameters is also offered. Examples of second-order low-pass filter calculations and simulation results are given, which confirm the correctness of the calculations. Also, the results of modeling universal and rejection filters are given.Документ Відкритий доступ Выбор критерия поддержания резонансного режима работы пьезопреобразователя(НТУУ «КПІ», 2010) Мовчанюк, А.
