I am doing a large end of high school project on some physics, which has to involve an experiment. In lieu of this, I bought myself a micro oscilloscope - RSO138 - which I would use to listen to data cables.
However, it has now dawned on me, that data transfer may be more about computer science than actual physics.
I can write a bit about the physical limitations of bandwidth - but that is about all I can imagine.
Is there any gold nugget of a topic I am missing in the physics of data transfer? (both audio and digital USB transfers).
