Circuit Arrangement For Suppressing Interfering Signals In Transmitted Signals Emitted By A Modem Of A Household Appliance |
摘要 |
A circuit arrangement for suppressing interfering signals in transmitted signals emitted by a modem of a household appliance equipped with a transmitting device for transmitting and a receiving device for receiving data signals, the modem containing a transmitting branch and a receiving branch. A low-pass filter for attenuating the interfering signals, which have interfering signal frequencies higher than the transmitted signal frequencies and which are emitted by a transmitter unit of the modem, is contained in the transmitting branch of the modem. In addition, a band elimination filter that filters out only the aforementioned interfering signals is connected upstream from the low-pass filter on the side of the transmitter unit.
