One other constraint is that with a transmission line the locus (as the line length increases) of the input reflection coefficient of the line must rotate in the clockwise direction. We call this Smith Chart a z/y Smith Chart.
If we now use this Smith Chart and rotate it for (upside down), and place it over the chart above, we will see that the impedance and admittance point are in the same position on the Smith Chart. Black And White Smith Chart Is Often Used In Smith Chart, Math Chart And. Only a few have survived in electrical engineering usage, with Smith charts being overwhelmingly the most important. The admittance is shown on Smith Chart in Figure fig:SC1-adm. \) to 1 needs to lie on these circles and the intermediate point will be where these circles intersect. This article offers an introduction to the Smith chart and how it’s used to make transmission-line calculations and fundamental impedance-matching circuits.
