发明名称 System and method for detecting fro locking
摘要 The detection of locking of a free running oscillator (FRO) is disclosed, including taking periodic samples of the FRO output, storing each new sample in a sample storage medium, each time a new sample is stored searching the stored samples for at least one repeating pattern, counting consecutive sampling instances in which a repeating pattern is found, and indicating when the count reaches a preselected threshold number.
