  • Signal input device
    Patent number: 5132649
    Abstract: A signal input device having a mutual inductor formed by a coil connected with a capacitor for a grounding cable in series and a coil connected with a capacitor for a signal cable in series, and a compensating capacitor connected with the series circuit composed of the capacitor and the coil on the grounding cable in parallel. The compensating capacitor serves to prevent occurrence of a voltage on the grounding cable, and accordingly only regular signals received by an antenna are transmitted. The mutual inductor prevents resonance of inductance of a lead terminal of the compensating capacitor with capacitance of the compensating capacitor.
