Abstract
For suppressing interference signals in a multiplex signal an RC member which is preceded by a voltage divider is used. The voltage divider consists of a resistor and two diodes which are connected in parallel and in opposite directions and which perform a limitation with respect to a reference signal taken from the output of a fedback differential amplifier. The output signal of the RC member is applied to the non-inverting input of the differential amplifier. The limitation is carried out with respect to a reference signal corresponding to the signal smoothed by the RC member.
