A scheme of simple band-pass RC- and LR- filters on operational amplifiers containing only one capacitor or inductor and 3 resistors is proposed. A comparison is made of the amplitude-frequency characteristics of the proposed filters, as well as the RC filter of Robert Allen Pease and its modified LR- variant.
