Abstract

A signal detector 100 and method detects digital signals on a signal path 102. The signal detector 100 comprises a sample detector 108 which detects digital code samples for past sample periods and the instant sample period. Past digital code samples are stored in a sample storage 114. Past digital code samples and the instant digital code sample are compared by a comparator 112. If the samples are equal, the signal path 102 is idle. If the samples are unequal, the signal path 102 is in use. It is contemplated that the past digital code sample substantially immediately preceding the instant digital code sample will be compared to the instant digital code sample.
