    摘要: An at least second-order active filter circuit includes an operational amplifier (Op) whose frequency response, in conjunction with an RC network (R1, R2, C1, C2), serves to set a predetermined low-pass characteristic. The frequency response of the operational amplifier (Op) forms an integral part of this low-pass characteristic.
