Simple Filter Topologies
The topologies shown in figure 1.7 are commonly used for filter and attenuator designs. The L-section is identical topology to the potential divider topology. The T-section is identical topology to the Y topology. The Π-section is identical topology to the Δ topology.
All these topologies can be viewed as a short section of a ladder topology. Longer sections would normally be described as ladder topology. These kinds of circuits are commonly analysed and characterised in terms of a two-port network.

Famous quotes containing the word simple:
“Here we are, we’re alone in the universe, there’s no God, it just seems that it all began by something as simple as sunlight striking on a piece of rock. And here we are. We’ve only got ourselves. Somehow, we’ve just got to make a go of it. We’ve only ourselves.”
—John Osborne (b. 1929)
