Abstract:
1. A method for suppressing a radiant noise of an electronic circuit having at least one signal transmission wire connected thereto, wherein the electronic circuit includes an electronic device having an earth terminal and at least one signal terminal, the earth terminal being connected to a housing of the electronic circuit via a common mode impedance, comprising the steps of: forming a plurality of current paths corresponding to one of said at least one signal transmission wire; transmitting an output signal of an electronic device to a corresponding signal transmission wire through a corresponding one of the current paths; flowing a current between an earth terminal of the electronic device and a quasi-ground through said one path; and radiating noise energy from the quasi-ground into said at least one signal transmission wire through the plurality of current paths to increase a noise level of said at least one signal transmission wire so that a noise level of said at least one signal transmission wire is equal to a noise level of the quasi-ground.
