When pressure testing a drop system to check for leakage, What must be done before applying the test signal? Answer The technician must isolate the drop system from the hybrid fiber/coax (HFC) network by disconnecting the drop at the distribution tap. Why do some leakage detection systems utilize a leakage carrier modulated with a tagging signal? Answer To avoid false detection of leaks. When all three sections of a pulse code modulator (PCM) are combined, what function can be performed? A...

Evaluating EWIs with the AUC The AUC (the area under the receiver operating characteristics curve, or ROC curve) is a statistical tool used in assessing the performance of signals that forecast binary events (ie events that either occur or do not). The term ROC reflects the origins of the tool in the analysis of radar signals during World War II, although it has a long tradition in other sciences (eg Swets and Picket (1982)). Its applications to economics are more recent (eg Cohen et a...
