Clicking on the start Button starts
the animation given the current transmission line and its parameters (See
Settings Panel). At this time, each graph of the applet is reinitialized
and the time is set to zero.
Clicking anywhere in the space/time plane will
stop the animation, erase each graph, and display all the values (voltage,
position, time) corresponding to the click location in the Display Panel.
Note : Doing this will prevent you from restarting the animation
from the clicked point. If you pause the animation using the “pause”
button, it can be restarted using the “continue” button.
(See Time Diagram).
The Bounce diagram
bounce diagram is a two dimensional representation of the transient waves
bouncing back and forth on the transmission line. Normalized position (x/L)
is represented horizontally and the normalized time (t/tau) vertically.
Zigzagging lines are drawn in the figure to indicate
the progress of the wave as a function of both the position x and the time
t. The direction of travel is from the bottom to the top.
For example, the first line
on the bounce diagram indicates that the initial wave takes a time tau
(i.e a normalized time of 1), to reach the load end of the line. It sets
up a reflected wave, which travels back to the source, reaching there at
a time of 2*tau (i.e a normalized time of 2), which then gives rise to
another reflected wave, and so on, with the process continuing indefinitely.
The vertical red line represents
a fixed position on the transmission line, for all the time of the animation.
The horizontal red line corresponds to the actual time of the animation.
