A family of a new subclass of fourth-order band-pass filters
Circuit solutions for a new subclass of fourth-order band-pass filters have been developed, which are implemented on operational amplifiers and have, among other things, paraphase outputs. Basic equations for their transfer function are obtained. In the Micro-Cap environment, computer simulation of the amplitude-frequency characteristics (AFC) was carried out, which shows the possibility of independent adjustment, adjustment of the bandwidth, uneven AFC and center frequency gain.
The research has been carried out at the expense of the Grant of the Russian Science Foundation (project No. 18-79-10109-P).
