Patent

CA 2468918

The invention relates to an analog bandpass filter comprising a plurality of LC ladder circuits (1), the response from which is determined by a passband (fpi, fps) and a rejection band (with limits fri and frs). The inventive filter is characterised in that a series of tank circuits (5) is disposed in parallel to the filter charge, the resonance frequencies of said tank circuits coinciding with the lower (fpi) and upper (fps) cut-off frequency of the pass- band of the filter. Furthermore, the filter comprises a control resistor (Rc) which regulates the effect of the tank circuits on the filter. Said structure can be used to compensate the effect of the real limitations of the LC components (1) in order to adjust the response from the analog bandpass filter created with said components to the response from the ideal bandpass filter.

Ce filtre passe-bande analogique comprend une pluralité de circuits LC (1) en escalier dont la réponse est déterminée par une bande passante (f¿pi?, f¿ps?) et une bande interdite (avec limites f¿ri? et f¿rs?). Ledit filtre se caractérise en ce que, en parallèle avec la charge du filtre, deux circuits bouchon (5) disposés en série, présentent des fréquences de résonance coïncidant avec la fréquence d'interruption inférieure (f¿pi?) et supérieure (f¿ps?) de la bande passante du filtre. De plus, ledit filtre comprend une résistance de contrôle (R¿c?) qui régule l'effet des circuits réservoir sur le filtre. Cette structure permet de compenser l'effet des limitations réelles des composants LC (1) pour régler la réponse du filtre passe-bande analogique créé avec ces deux composants en réponse au filtre passe-bande idéal.
