摘要：
A frequency selective circuit arrangement having a resistor network connected to a supply line and feeding an auxiliary four terminal filter network whose attenuation characteristic curve is variable under the control of means for varying the terminating resistance of said four terminal network, the impedance of the elements having a predetermined frequency position for the peaks of the attenuation characteristic of the arrangement.
