ABSTRACT:
A balanced filter circuit includes only one balanced amplifier (10) having an inverting input (6) and a non-inverting input (5) and an inverting output (7) and a non-inverting output (8) for realization of filter transfer functions Uout/Uin of the second or higher order from an input signal Uin at input terminals (1, 2) to an output signal Uout at output terminals (3, 4) having passive admittances which are composed of a parallel-combination of a resistor (R42, R44) and/or a capacitor (C41, C44) and/or a number of series-combinations of a resistor (R41, R43, R45) and a capacitor (C42, C43, C45).
