Abstract
A new topology of the band-pass active RC filter (BP) based on the classic Wien bridge is proposed. This scheme, implemented on two Op-Amps, is recommended for the use as a second-order link in more complex BPs. The analysis of the modified band-pass ARC filter is carried out, the main parameters of the BP are found. The computer simulation of the developed PF tuning algorithm is completed. The graphs of changes in the frequency response and phase response when changing various parameters of the BP are obtained. It is shown that in the considered BP an independent adjustment of the main parameters is ensured - transmission coefficient in the passband, pole attenuation and pole frequency.
