NOISE SUPPRESSING CIRCUIT |
摘要 |
<p>A noise suppressing circuit comprises a winding (11a) inserted at a first position (P11) in a conduction line (3); a winding (11b) coupled to the winding (11a); an insertion signal transmission path (19); and an inductance element (13). One end of the insertion signal transmission path (19) is connected, at a second position (P12), to the conduction line (3), while the other end of the insertion signal transmission path (19) is connected to a conduction line (4). The winding (11b) is inserted in the insertion signal transmission path (19). The insertion signal transmission path (19) is used for transmitting an insertion signal that is produced, based on a signal corresponding to the noise detected from the conduction line (3), and that is to be inserted in the conduction line (3) so as to suppress the noise. The inductance element (13) is inserted in the conduction line (3) between the positions (P11,P12). The number of turns of the winding (11b) is greater than that of the winding (11a).</p> |
