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.
