Abstract
A first bypass-type condenser for normal mode noise is connected between the input terminals of a pair of signal paths and a pair of further bypass-type condensers for common mode noise are each connected between a respective one of the signal paths and ground. The pair of further bypass-type condensers each comprise a three-terminal condenser having a pair of lead terminals each provided with a bead core thereon, whereby noise passing through the line filter can be effectively eliminated, while also eliminating spurious LC resonance effects at ultra-high frequencies.
