Abstract

In many digital communications systems, synchronization is achieved by detection of adigital pattern which is repeated regularly. An enable signal or "window" can be used to reduce the likelihood of a false detection by disabling the detector circuits between transmissions of the sync pattern. However, prior to acquisition of synchronization, a narrow window can significantly hamper efforts to detect sync. Thus it is desirable to generate a window signal which is open until sync is acquired and then narrows while the sync is locked.
