Z Plane Phase Surface
Plot 1R Pole 1R Zero
Cuthbert Nyack
The phase of the Z transform of a system, with a pole at -a and a zero at
-z, is shown in the applet below for Z within the unit circle.
When th = 0 the view is along the -ve real axis.
ph changes the elevation above the Z plane.
mr magnifies the plot.
Vertical axis varies from -pi (blue) to +pi (red).
