Instructions:

1. The green graphics area can be scaled to any size. Just click on it and adjust handles. The applet has a maximum horizontal size, however, of approximatelly 950 px.
2. Parameters set through sliders are totally independent. User has the freedom to adjust parameters to solve a specific problem.
3. Parameter values and control buttons can be accessed (hidden) by clicking on the +(-) symbol to the right of the slider
4. Fine tuning can be achieved by clicking the +/- control buttons.
5. Play and pause control buttons allow running animations.
6. Parameter values can be entered in value windows as well.
7. Relative distance from load can be used to measure relative displacements along the transmission line.
8. Phase angle allows determining the phase of the reflection coefficient.
9. Relative shifted circle position can be used for solving double stub matching problems.
