In electronics, the " immittance " Smith chart simply has both the impedance and admittance grids on the same chart, which is useful for cascading series-connected with parallel-connected electric circuits.
22.
Use of the Smith chart and the interpretation of the results obtained using it requires a good understanding of AC circuit theory and transmission line theory, both of which are pre-requisites for RF engineers.
23.
If it applies to one port only ( being of the form S _ { nn } \, ), it may be displayed on an impedance or admittance Smith Chart normalised to the system impedance.
24.
The Smith Chart allows simple conversion between the S _ { nn } \, parameter, equivalent to the voltage reflection coefficient and the associated ( normalised ) impedance ( or admittance )'seen'at that port.
25.
Other such examples include the Smith chart, a graphical calculator used in electronics and systems analysis, thermodynamic diagrams and tephigrams, used to plot the vertical structure of the atmosphere and perform calculations on its stability and humidity content.
26.
If the termination was a perfect open or short circuit the magnitude of the voltage reflection coefficient would be unity, all power would be reflected and the point would lie at some point on the unity circumference circle of the Smith chart.
27.
Most RF network analyzers incorporate features including linear and logarithmic sweeps, linear and log formats, polar plots, Smith charts, etc . Trace markers, limit lines and also pass / fail criteria may also be added in many instances.
28.
The Smith chart graphical equivalent of using the transmission line equation is to normalise Z _ L \,, to plot the resulting point on a Z Smith chart and to draw a circle through that point centred at the Smith chart centre.
