<p>You - Coax - and Smith: A guide to drawing and using the Smith Chart with transmission lines, takes the reader through AC impedance measurements and transformation to polar coordinates as the smith chart. It includes several applications such as determining the impedance of a transmission line, design of matching stubs. Instruction on how to draw the smith chart from scratch are also given. The mathematics is reduced to a sequence of drawings, using plane geometry as the main mathematics tool.</p>
