[snip] I'm afraid you are wrong in so many ways. A digital signal does not have periodicity - it is just a stream of bits. It is sent over analogue transmission paths as a square wave. The receiver of the signal decodes the square-wave signal and also extracts the timing information from the same signal. As Pat as already pointed out, jitter is caused by errors in detecting the transition between 1 and 0 in the square wave in the analogue domain, which causes timing errors. So, the space between samples varies from the "standard" (for 44.1kHz sample rate)1/1,411,200 of a second. This means that the analogue signal reconstituted from the digital signal has different frequency content than the original input signal.
