Ok, y'all know about digital recording and sampling, then?

Ok, tell me then, does dithering:
1) Get rid of correlated artifacts due to quantization completely (no, won't get rid of correlated artifacts due to anything else)
2) Get rid of them partially
3) Mask them

What is the interchannel resolution (in time units)of a high frequency signal between the two channels of a Redbook CD. Pick the answer that's closest.

1) 1/44100 seconds
2) 2/44100 seconds
3) 1/(44100*65546) seconds
4) pi/(44100*16484) seconds
5) 1/(pi*22050*65536) seconds

What is the meaning of the "beating" that is reported to occur when a sine wave near 20kHz is sampled at 44100 Hz?
1) It shows that the sampling theorem doesn't work.
2) It shows that somebody forgot to use an anti-imaging filter
3) It shows that somebody put the probe at the wrong place in the circuit
4) It shows extra in-band sine waves that result from sampling errors.
