摘要

提出了一种基于经典维恩桥的带通有源RC滤波器(BP)拓扑结构。该方案在两个运放上实现，建议在更复杂的bp中用作二阶链路。对改进后的带通ARC滤波器进行了分析，找出了BP的主要参数。并对所开发的PF调谐算法进行了计算机仿真。得到了改变BP各参数时频率响应和相位响应的变化曲线图。结果表明，在考虑的BP中，保证了主要参数——通带传输系数、极点衰减和极点频率的独立调节。

Band-Pass ARC-Filter Based on the Classical Wien Bridge with the Pole Frequency Rise and Independent Adjustment of the Main Parameters

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.
