Abstract: Based on classical structures with a great amount of elements and feedback, the existent programming products calculating electrical filters do not make it possible to change the main parameters within certain ranges. The main point underlying the creation of a new program, calculating and designing changeable active filters, is to find an INSTRIMENT that would enable to carry out the synthesis of an active filter with the help of simple and effective structures. An instrument that would allow to on-line track the changes in amplitude-frequency characteristic while tuning electroscheme and selecting facevalues of elements available.
Keywords: filter, active filter, peak-frequency characteristic, information security, modeling
