Smith chart

The Smith chart is actually constructed on such a polar diagram.

The Smith chart is most frequently used at or within the unity radius region.

Optimal matching circuits can be designed for a particular system using Smith charts.

The Smith chart may also be used for lumped element matching and analysis problems.

The conversion may be read directly from the Smith chart or by substitution into the equation.

The reflection coefficient is displayed graphically using a Smith chart.

Another such example is the Smith chart, a graphical calculator used in electronics and systems analysis.

Smith charts can also be used to determine what length line to use to obtain a desired reactance.

The Smith chart has circumferential scaling in wavelengths and degrees.

In this case the wavelength scaling on the Smith chart circumference is not used.

Provided the frequencies are sufficiently close, the resulting Smith chart points may be joined by straight lines to create a locus.

The following table gives some similar examples of points which are plotted on the Z Smith chart.

Actual impedances and admittances must be normalised before using them on a Smith chart.

The Smith chart serves in radio electronics.

Often these will be scaled as Smith Charts.

These are the equations which are used to construct the Z Smith chart.

For these a dual (normalised) impedance and admittance Smith chart may be used.

As is the same as the system impedance, this is represented by a point at the centre of the Smith chart.

A locus of points on a Smith chart covering a range of frequencies can be used to visually represent:

In the complex reflection coefficient plane the Smith chart occupies a circle of unity radius centred at the origin.

The following circuit will be analyzed using a Smith chart at an operating frequency of 100 MHz.

The analysis starts with a Z Smith chart looking into R only with no other components present.

In most Smith chart problems however, losses can be assumed negligible () and the task of solving them is greatly simplified.

The length of the line would then be scaled to P assuming the Smith chart radius to be unity.
