Phase Surface Plot 1 Real Pole

Cuthbert Nyack
The applet below shows a surface plot of the phase of the Laplace Transform of a system with a pole at -a. When th = 0 the view is along the -ve real axis.
ph changes the elevation above the s plane.
mr magnifies the plot.
z axis varies from -pi (blue) to +pi (red).
