Elucidation of cause of electromagnetic noise allows for EM noise-less electric circuits

Most common devices are driven and controlled by electric power. Signals and power can be sent by transferring electricity through an electric circuit made up of conductors that conduct electrical current. However, interactions between a circuit and its environment, such as the ground and the earth, generate EM noise, causing malfunctions and generating heat. The equations developed in this study theoretically verified that EM noise was caused not only by the interference between transmission lines, but also by conditions of elements connected to the electric circuit.
