Smithin kartta, yksinkertaistettu versio opetuskäyttöön. Kirjassa on selitetty, miten voit itse piirtää diagrammin haluamallasi tarkkuudella.
Tämän sivun \LaTeX-koodi on myös saatavana netistä.
Tarkempi kartta on mm. Piirianalyysi 2:n nettisivulla {\em http://www.ct.tkk.f\/i/courses/ca2/smith.pdf}\\
