Abstract

1527866 Interference suppression TOYOTA JIDOSHA KOGYO KK 31 Oct 1975 [31 July 1975] 45194/75 Heading H4R In vehicle mounted circuitry electrical interference is suppressed by a trap wire of low impedance connected to a conductor wire in which a standing wave is formed, the connection of the trap wire being at what would be a nodal point if the trap wire were not there. The trap wire is an odd number of quarter wavelengths of the interfering current and is used to suppress currents in a demister wire in circumstances where an FM antenna is positioned on the rear window together with the demister.
