  • Patent number: 10340686
    Abstract: An electronic device that has a circuit network therein and conducts at least one of power reception and communication with an external device through a wire harness includes a detection circuit and a resonance frequency shift circuit. The detection circuit detects a voltage variation caused by a noise that has a frequency component near a resonance frequency and superimposes on at least one of the wire harness and the circuit network. The resonance frequency is determined based on a characteristic impedance of the wire harness and the circuit network. The resonance frequency shift circuit shifts the resonance frequency by changing at least one of a capacitance and an inductance of the circuit network based on a level of the voltage variation detected by the detection circuit.
