Just press play, and mess with the sliders to see what happens. For people who know about this stuff: Still mess with the sliders. JK, create your own simulation of a DIGITAL (the new stuff) signal, either for a coax cable, or a wireless signal. Danger! You can't output this to a real cable or signal. So beware of your feelings to be hurt.
This project is WAY more simple than you may realize. Just have a look to see how small it is. This was supposed to be an ANALOG (the old stuff) simulator, but the way I did it was so much easier for me to make it. With analog, it would just stay in place, and I even tried it 14 different ways! Thanks to my interests for helping with this project. (Technically the actual creator, but it sounds better to my ears to say I made it up.) Mhz, Khz, or Ghz would have either froze the project, way too glitchy, or would completely destroy your PC.
