Physics help

[BigMoosie]

hi guys, i have an assessment task due in two (2) days for my year 11 physics, me beeing foolish me has left it two weeks since being handed out. neway, i was hoping someone would know a good site that would talk about how analogue and digital communication work and how they compare, doesnt need to be too heavy or in depth as this is just the start of the course,

-even if you dont know specific page a broad site might be helpful anyway, thanx for your time.

Analogue: comes in a sinusoidal wave.
Digital: comes in 1's and 0's

Analogue: A(mplitude)M(odulation) and F(requency)M(odulation)
Digital: Yes and No

Analogue: loss by noise over distances
Digital: little loss even over huge distances

Analogue: origional quality is maintained for small distances, but lost on long distances
Digital: Origional quality lost in short distances but does not decay with distance

Need any more help? If so you'll have to give a little more info on what your after.
