A circuit arrangement for suppressing interfering signals in the receiving branch of a modem containing a transmitting branch and the receiving branch, of a household appliance equipped with a transmitting device for transmitting and a receiving device for receiving data signals. When using a receiving circuit of the modem with an input circuit having a relatively high input impedance compared with the impedance of a useful signal source delivering data signals, to which data signals are supplied by the useful signal source having a relatively low impedance in comparison and in the presence of the interfering signal sources which deliver the interfering signals which have a relatively high impedance, an ohmic resistance is connected in parallel to the input circuit with a relatively low resistance compared to the input impedance.
