3.2. Analysis of Second Subcircuit. When dividing the common X-circuit, the second subcircuit between the nodes X and Z forms in Figure 12 a current divider. Analogously to the first subcircuit, the ...

A signal flow graph (SFG) representation of small-signal responses of nonlinear microwave circuits around a large-signal operating point is developed using the X-parameters. It is shown that, unlike ...

The equations characterizing a systems problem may be expressed as a network of directed branches. (The block diagram of a servomechanism is a familiar example.) A study of the topological properties ...
