Abstract (en)
[origin: WO2006005750A1] The invention relates to a circuit arrangement for suppressing interfering signals in transmitted signals emitted by a modem (MO) of a household appliance (HG) equipped with a transmitting device for transmitting and a receiving device for receiving data signals, said modem containing a transmitting branch and a receiving branch. To this end, a low-pass filter (TP) for attenuating the interfering signals, which have interfering signal frequencies higher than the transmitted signal frequencies and which are emitted by a transmitter unit (SB) of the modem (MO), is contained in the transmitting branch of the modem (MO). In addition, a band elimination filter (BS) that filters out only the aforementioned interfering signals is connected upstream from the low-pass filter (TP) on the side of the transmitter unit (SB).
