Abstract
A phase detection method and apparatus, and a storage medium and an electronic apparatus are provided. A sampling operation is performed on a clock signal to be detected to obtain binary sequences. Phase intervals of the clock signal to be detected in initial sampling periods are determined, according to the binary sequences, as first phase intervals. Based on a reference phase interval in the first phase intervals, a standardization operation is performed on other phase intervals in the first phase intervals to obtain second phase intervals, wherein the reference phase interval is a phase interval determined within a first sampling period after the sampling operation is triggered, and the other phase intervals are phase intervals determined within sampling periods following the first sampling period. The second phase intervals are converged, and phase information of the clock signal to be detected is obtained according to the converged second phase intervals.
