Title (EN) AN ELECTRONIC FILTER AND AN ELECTRONIC CIRCUIT FOR USE IN A SWITCHING APPLICATION
(FR) FILTRE ÉLECTRONIQUE ET CIRCUIT ÉLECTRONIQUE DESTINÉS À ÊTRE UTILISÉS DANS UNE APPLICATION DE COMMUTATION
Abstract:
(EN) An electronic filter (100) comprising: a filter section (102, 104); an impedance correction section (106 and 108) that is electrically coupled to the filter section (102, 104); and a circuit altering section (110-116) that is arranged to alter at least one property of the impedance correction section (106, 108) to effect a shift in a resonant frequency of the impedance correction section (106, 108) from with a pass band of the filter section to within a stop band of the filter section (102, 104).
(FR) L'invention concerne un filtre électronique (100) comprenant: une section de filtre (102, 104); une section de correction d'impédance (106 et 108) couplée par voie électrique à la section de filtre (102, 104); et une section de modification de circuit (110-116) conçue pour modifier au moins une propriété de la section de correction d'impédance (106, 108) afin d'obtenir un changement dans la fréquence de résonance de la section de correction d'impédance (106, 108) allant d'une bande passante de la section de filtre à une bande d'arrêt de la section de filtre (102, 104).
