An antimetric electrical network is an electrical network that exhibits anti-symmetrical electrical properties. The term is often encountered in filter theory, but it applies to general electrical network analysis. Antimetric is the diametrical opposite of symmetric; it does not merely mean "asymmetric" (i.e., "lacking symmetry").
Unbalanced, asymmetrical circuit. Fig. 2. Unbalanced, symmetrical circuit. Fig. 3. Balanced, asymmetrical circuit. Fig. 4. Balanced, symmetrical circuit. A balanced circuit will normally show a symmetry of its components about a horizontal line midway between the two conductors (example in figure 3). This is different from what is normally ...
Reciprocity in electrical networks is a property of a circuit that relates voltages and currents at two points. The reciprocity theorem states that the current at one point in a circuit due to a voltage at a second point is the same as the current at the second point due to the same voltage at the first.
In electrical engineering, the method of symmetrical components simplifies analysis of unbalanced three-phase power systems under both normal and abnormal conditions. The basic idea is that an asymmetrical set of N phasors can be expressed as a linear combination of N symmetrical sets of phasors by means of a complex linear transformation. [1]
For a symmetrical network, the iterative impedance and image impedance are identical and are the same at both ports. This impedance is sometimes called the network's characteristic impedance, a term usually reserved for transmission lines. [10] The model for a transmission line is an infinite chain of L-sections with infinitesimally small ...
The Wilkinson design can also be used as a power combiner because it is made up of passive components and hence is reciprocal. First published by Ernest J. Wilkinson in 1960, [ 1 ] this circuit finds wide use in radio frequency communication systems utilizing multiple channels since the high degree of isolation between the output ports prevents ...
