barcode in vb.net 2010 The GB Plane in Software
The GB Plane Decoding Code39 In None Using Barcode Control SDK for Software Control to generate, create, read, scan barcode image in Software applications. Code39 Generator In None Using Barcode generator for Software Control to generate, create Code39 image in Software applications. Admittance can be depicted on a plane similar to the complex impedance (RX ) plane. Actually, it s a half plane, because there is ordinarily no such thing as negative conductance. (You can t have a component that conducts worse than not at all.) Conductance is plotted along the horizontal, or G, axis on this coordinate half plane, and susceptance is plotted along the B axis. The GB plane is shown in Fig. 159, with several points plotted. Code 3/9 Recognizer In None Using Barcode reader for Software Control to read, scan read, scan image in Software applications. Generating Code 3/9 In Visual C#.NET Using Barcode creator for VS .NET Control to generate, create Code39 image in Visual Studio .NET applications. It s Inside Out The GB plane looks superficially identical to the RX plane. But mathematically, the two could not be more different! The GB plane is mathematically inside out with respect to the RX plane. The center, or origin, of the GB plane represents the point at which there is no conduction for dc or for ac. It is the zeroadmittance point, rather than the zeroimpedance point. In the RX plane, the origin represents a perfect short circuit, but in the GB plane, the origin corresponds to a perfect open circuit. As you move out toward the right (east) along the G, or conductance, axis of the GB plane, the conductance improves, and the current gets greater. When you move upward (north) along the jB axis from the origin, you have everincreasing positive (capacitive) susceptance. When you go down (south) along the jB axis from the origin, you encounter increasingly negative (inductive) susceptance.

Barcode Creation In None Using Barcode encoder for Software Control to generate, create barcode image in Software applications. Vector Representation of Admittance Complex admittances can be shown as vectors, just as can complex impedances. In Fig. 1510, the points from Fig. 159 are rendered as vectors. Generally, long vectors in the GB plane indicate large currents, and short vectors indicate small currents. Imagine a point moving around on the GB plane, and think of the vector getting longer and shorter and changing direction. Vectors pointing generally northeast, or upward and to the right, correspond to conductances and capacitances in parallel. Vectors pointing in a more or less southeasterly direction, or downward and to the right, are conductances and inductances in parallel.
