Using the Smith chart, the normalised impedance may be obtained with appreciable accuracy by plotting the point representing the reflection coefficient " treating the Smith chart as a polar diagram " and then reading its value directly using the characteristic Smith chart scaling.

Use of the Smith chart utility has grown steadily over the years and it is still widely used today, not only as a problem solving aid, but as a graphical demonstrator of how many RF parameters behave at one or more frequencies, an alternative to using tabular information.

When asked why he invented the chart, Smith explained, " From the time I could operate a slide rule, I've been interested in graphical representations of mathematical relationships . " In 1969 he published the book " Electronic Applications of the Smith Chart : In Waveguide, Circuit, and Component Analysis ", a comprehensive work on the subject.

Conversely, if Z 0, i > Z 0, the impedance curve should be off-centred towards the + x axis . Because the characteristic impedance of each transmission line segment Z 0, i is often different from that of the input cable Z 0, the impedance transformation circle is off-centred along the x axis of the Smith Chart whose impedance representation is usually normalized against Z 0.
