Digital Audio Fundamentals 415Figure 14.4 : An ideal binary signal (a) has two levels. After transmission it may look like
(b), but after slicing the two levels can be recovered. Noise on a sliced signal can result in
jitter (c), but reclocking combined with slicing makes the fi nal signal identical to the
original as shown in (d).
