Analysis of electrical filters in high level language C + +

Abstract

Article presents a synthesis system of active electric filters on the basis of its mathematical models provided by linear transfer functions. Each filter is implemented to operational amplifiers, resistors and capacitors. All filter elements are linear, concentrated and invariant over time.The initial data for the synthesis filters are the cut-off frequency response model of dynamic links and angles of inclination to the axis (dB / decade). Initial data for calculation of filters are the nominal values of capacitors stored in the corresponding file. The developed system has the ability to expand at the expense of updating files that contain the concepts of unit cells of active filters and nominal values of capacitors.
