Z transforms visualized on the complex plane
, by Joe Dellinger, Clement Kostov, and Fabio Rocca
Z transforms provide a unifying framework for designing filters and understanding their
properties. Unfortunately, Z transforms are not very intuitive. To remedy this situation
for students at SEP, we have developed a program to display Z transforms on the complex
plane. We display several different filters, and show how their properties are visible
in the plot.
