Electronic filter topology
From Wikipedia, the free encyclopedia
An electronic filter topology is an electronic analog filter circuit in which the values of the components remain undefined. A particular topology is then characterized entirely by the manner in which the components are connected, and not by their values.
There are many different types of electronic filters and they are characterized by their transfer function, but not by any particular topology. Once the transfer function for a filter is chosen, it remains to select the particular topology to implement that filter. For example, one might choose to design a Butterworth filter using the Sallen Key topology.
