Impedance and admittance
The combination of the reflection/transmission polar plots, nomographs, and the impedance and admittance Smith chart leads to the combined Smith chart (see Figure \(\PageIndex{11}\)). This color Smith chart is the preferred version for use in design and the separate impedance and admittance versions of the Smith chart are rarely used.5.2: Bus Admittance. Now, if the network itself is linear, interconnections between buses and between buses and ground can all be summarized in a multiport bus impedance matrix or its inverse, the bus admittance matrix. As it turns out, the admittance matrix is easy to formulate. The network consists of a number Nb N b of buses and another ...
