Synthesis and Analysis of Low-Pass And High-Pass Biquadratic Active Filters Using Computer-Based Tools

In this paper, low-pass and high-pass biquadratic active filters are synthesized and analyzed. This is done according to a set normalized voltage transfer function and with known normalizing resistance and cut-off frequency. The synthesis is realized through MATLAB, and the analysis of the designed filters after the selection of standard values of the resistances of the resistors and of the capacitances of the capacitors in the synthesized circuits is carried out through MicroCAP and NI Multisim, used for the simulation of analog and digital circuits. The findings will be utilized in the educational process of the “Communication Circuits“ course, which is taken by students specializing in “Internet and Mobile Communications” at the undergraduate level.
