Electronic filter topology defines electronic filter circuits without taking note of the values of the components used but only the manner in which those components are connected. Filter design characterises filter circuits primarily by their transfer function rather than their topology. Transfer functions may be linear or nonlinear. Common types of linear filter transfer function are; high-pass, low-pass, bandpass, band-reject or notch and all-pass. Once the transfer function for a filter is chosen, the particular topology to implement such a prototype filter can be selected so that, for example, one might choose to design a Butterworth filter using the Sallen–Key topology.

rdfs:comment	Filtr drabinkowy (filtr Zobela, ang. ladder-type filter) – filtr utworzony poprzez połączenie ze sobą kilku filtrów (ogniw lub półogniw) podstawowych. Nazwa filtru pochodzi od sposobu rozmieszczenia elementów na schemacie elektrycznym. Kolejne elementy (ogniwa) filtru drabinkowego muszą być do siebie dopasowane falowo. Filtry Zobela (RC) stosuje się do korekcji charakterystyki impedancyjnej i częstotliwościowej w urządzeniach elektroakustycznych (na wyjściu wzmacniaczy mocy).

(en) La topologia dei filtri elettronici definisce i circuiti dei filtri elettronici senza tenere conto dei valori dei componenti utilizzati ma solo del modo in cui tali componenti sono connessi. La progettazione di un filtro caratterizza principalmente i circuiti del filtro in base alla loro funzione di trasferimento piuttosto che in base alla loro topologia. Le funzioni di trasferimetno possono essere lineari o non lineari. I tipi comuni di funzione di trasferimento di filtri lineari sono: passa-alto, passa-basso, passa-banda, elimina-banda o notch e passa-tutto. Una volta scelta la funzione di trasferimento per un filtro, la particolare topologia per implementare per un tale filtro prototipo può essere selezionata in modo tale che, per esempio, si potrebbe scegliere di progettare un filtro B (it) Ett bikvadratiskt filter är en typ av linjärt filter vars överföringsfunktion utgörs av en kvot mellan två funktioner med kvadratiska termer (andragradstermer). Bikvadratiska filter implementeras oftast som . Ett specialfall av bikvadratiskt filter är lågpassfilter som har polynomet: med överföringsfunktionen Om dämpfaktorn definieras som blir beloppsfunktionen och Enligt figur 1 kan bikvadratiska filter ge upphov till en mer eller mindre uttalad puckel runt brytfrekvensen. Det går att visa att denna hamnar vid och amplituden hos puckeln är Ett Butterworthfilter har det normaliserade polynomet (sv)
