Not necessarily white - multipath interference results in ghosting. But 
then, so do certain compression artifacts, so...

Indeed. Analogue goes from crystal clear to utterly unrecognisable in a 
smooth progression. Digital goes from crystal clear to nothing at all in 
a single big jump.

Still, digital gives you the possibility to use error-correcting codes 
to try to combat poor reception. And boosting a digital signal offers 
more possibilities for error correction than in an analogue system.

Clearly my TV must be *very* bad. I've yet to see any compression 
artifacts in any digital broadcast or DVD. (Except some of the DVDs I 
burned myself...)
