The set of current loop equations associated with the tie sets of the original graph and tree is identical to the set of voltage node-pair equations associated with the cut sets of the dual graph. [40] The following table lists dual concepts in topology related to circuit theory. [41] Figure 2.5. The dual graph of the graph in figure 2.2.
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.
Indeed, a graph has treewidth at most 2 if and only if it has branchwidth at most 2, if and only if every biconnected component is a series–parallel graph. [4] [5] The maximal series–parallel graphs, graphs to which no additional edges can be added without destroying their series–parallel structure, are exactly the 2-trees.
Representation of a lumped model consisting of a voltage source and a resistor. The lumped-element model (also called lumped-parameter model, or lumped-component model) is a simplified representation of a physical system or circuit that assumes all components are concentrated at a single point and their behavior can be described by idealized mathematical models.
Once a lattice circuit has been developed, it is often desirable to convert the result into an unbalanced form, [20]: 268, [23]: 168 so that the circuit can be used in systems with an earth plane. [ 22 ] : 352 Furthermore, there are other benefits to be gained from the conversion process, such as a reduced component count and less stringent ...
Similar to the buck-boost converter with inverting topology, the output voltage of non-isolated Ćuk converter is typically inverted, with lower or higher values with respect to the input voltage. While DC-to-DC converters usually use the inductor as a main energy-storage component, the Ćuk converter instead uses the capacitor as the main ...
The circuit signal is provided by an AC Norton source (current I S, Norton resistance R S) at the input, and the circuit has a resistor load R L at the output. As mentioned earlier, this amplifier is bilateral as a consequence of the output resistance r O , which connects the output to the input.
It is possible to use the Bartlett transformation in reverse; that is, to transform a symmetrical lattice network into some other symmetrical topology. The examples shown above could just as equally have been shown in reverse. However, unlike the examples above, the result is not always physically realisable with linear passive components.
