    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.

    Balanced bridged-T topology; Open-circuit L-section topology; Short-circuit L-section topology; Balanced open-circuit C-section topology; Balanced short-circuit C-section topology; The bridged-T topology is also used in sections intended to produce a signal delay but in this case no resistive components are used in the design.

    en.wikipedia.org/wiki/Π_pad

    A general L-section circuit with shunt admittance Y and series impedance Z. The values of resistance of the attenuator's elements can be calculated using image parameter theory. The starting point here is the image impedances of the L section in figure 2. The image admittance of the input is,

    Filters using passive filter and active filter technology can be further classified by the particular electronic filter topology used to implement them. Any given filter transfer function may be implemented in any electronic filter topology. Some common circuit topologies are: Cauer topology – passive; Sallen–Key topology – active

    A general L-section circuit with series impedance Z and shunt admittance Y. The values of resistance of the attenuator's elements can be calculated using image parameter theory. The starting point here is the image impedances of the L section in figure 2. The image impedance of the input is,

  9. Lattice network - Wikipedia

    en.wikipedia.org/wiki/Lattice_network

    As shown, an inductor L a shunts Z a ′ and an inductor L b is in series with Z b ′. This leads to the alternative bridged-T circuit on the right. If L a > L b, then the negative-valued inductor can be achieved by means of mutually coupled coils. To achieve a negative mutual inductance, the two coupled inductors L1 and L2 are wound 'series ...
