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:
“Your apple face, the simple crèche
Of your arms, the August smells
Of your skin. Then I sorted your clothes
And the loves you had left, Elizabeth,
Elizabeth, until you were gone.”
—Anne Sexton (1928–1974)
