<p>A noise suppressing circuit capable of suppressing noise over a wide frequency range while reducing the size. The noise suppressing circuit comprises first and second inductors (51, 52) inserted in series in a first conductor (3), and a series circuit (15) of a third inductor (53) and a first capacitor (14). The series circuit (15) has one end connected between the first and second inductors (51, 52) and the other end connected to a second conductor (4). Even if the coupling coefficient k of the first and second inductors (51, 52) is smaller than 1, a damping characteristic substantially identical or similar to the ideal characteristic can be obtained by adjusting the value of the inductance (L3) of the third inductor (53) depending on the value of the coupling coefficient k.</p> |
