electronic filter topology

Any given filter transfer function may be implemented in any electronic filter topology.

Active filter circuit configurations (electronic filter topology) include:

Filters using passive filter and active filter technology can be further classified by the particular electronic filter topology used to implement them.

The Sallen-Key topology is an electronic filter topology used to implement second-order active filters that is particularly valued for its simplicity.

There are many variations on ladder topology, some of which are discussed in the Electronic filter topology and Composite image filter articles.

Multiple feedback topology is an electronic filter topology which is used to implement an electronic filter by adding two poles to the transfer function.

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.

Here "L" should not be confused with the inductance L - in electronic filter topology, "L" refers to the specific filter shape which resembles inverted letter "L".

In his 2000 interview with Allyn Jackson of the American Mathematical Society, he explained that he sees "networks as discrete versions of harmonic theory", so his experience with network synthesis and electronic filter topology introduced him to algebraic topology.
