One of my questions regarding the BYTE test involves the
introduced noise used. I was under the impression that the most
frequent noise problem in T-carrier is 'phase hits' or abrupt
changes in phase. Is the multicarrier method more immune to
this or not? Does the noise the reviewers used produce phase
hits?
