A practical circuit diagram would use the specific symbols for resistors, inductors, capacitors etc., but topology is not concerned with the type of component in the network, so the symbol for a general impedance has been used instead. The Graph theory section of this article gives an alternative method of representing networks.
The bridged-T delay equaliser is an electrical all-pass filter circuit utilising bridged-T topology whose purpose is to insert an (ideally) constant delay at all frequencies in the signal path. It is a class of image filter .
An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.
Multiple feedback topology circuit. Multiple feedback topology is an electronic filter topology which is used to implement an electronic filter by adding two poles to the transfer function. A diagram of the circuit topology for a second order low pass filter is shown in the figure on the right.
The simple conversion procedure shown in the previous section can only be applied in a limited set of conditions – generally, some form of bridged-T circuit is necessary. Many of the conversions require the inclusion of a 1:1 ideal transformer, [ 14 ] but there are some configurations which avoid this requirement, and one example is shown below.
Lattice filter topology. A lattice phase equaliser or lattice filter is an example of an all-pass filter.That is, the attenuation of the filter is constant at all frequencies but the relative phase between input and output varies with frequency.
Additional pictures illustrate the circuit operation by visualizing the voltage relief and current topology at low input voltage (logical "0"), during the transition and at high input voltage (logical "1"). ECL is based on an emitter-coupled (long-tailed) pair, shaded red in the figure on the right. The left half of the pair (shaded yellow ...
The diode and the switch are simplified as either a short circuit when they are on or by an open circuit when they are off. When in the off-state, the capacitor C is charged by the input source through the inductor L 1. When in the on-state, the capacitor C transfers the energy to the output capacitor through the inductance L 2.
