ABSTRACT:
A fitter comprising a first (R.sub.1) and a second (R.sub.2) resistor arranged in series between an input terminal (5) for receiving an input voltage (v.sub.i) and the input (2) of an amplifier. The amplifier (1) comprises a transistor (T.sub.1) whose base is coupled to the input (2), whose emitter is coupled to a first output (3) and via a current source (I.sub.1) to ground, and whose collector is coupled to a second output (4) and via a third resistor (R.sub.3) to the positive power-supply terminal. A first capacitor (C.sub.1) is arranged between the junction point (6) between the first resistor (R.sub.1) and the second resistor (R.sub.2) and the first output and a second capacitor (C.sub.2) is arranged between the input (2) and ground. A signal having a second-order low-pass characteristic is taken from the first output and a signal having a second-order high-pass characteristic is taken from the second output.
