Abstract(in Japanese) (See Japanese page)
Abstract(in English) Almost all the noise filters used in city, are composite of L and C. Then their impedances are reactive and phase angles are near 90°. If the filter connect to power supply line, there are series resonant frequencies between them, and then the noise currents of that frequencies will be through out the filter. Other case, as the lines impedance have many parallel resonance circuits, when pulse current flow in them, dampued oscillation namely disturbance noises will be occurred. The proposed filter is modified bridged T circuit and its impedance is resistive and phase angles are within 45° for wide frequency range. Then they are no series resonance and no dampued oscillation.
