PHASE DETECTION METHOD AND APPARATUS, AND STORAGE MEDIUM AND ELECTRONIC APPARATUS

Document Type and Number:

WIPO Patent Application WO/2020/073574

Kind Code:

A1

Abstract:

A phase detection method and apparatus, and a storage medium and an electronic apparatus. The method comprises: performing a sampling operation on a clock signal to be detected to obtain a binary sequence (S12); determining, according to the binary sequence, a phase interval of said clock signal in an initial sampling period, and taking same as a first phase interval (S14); performing a standardization operation on the other phase intervals comprised in the first phase interval using a reference phase interval comprised in the first phase interval to obtain a second phase interval, 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 after the sampling operation is triggered (S16); and converging the second phase interval, and obtaining phase information of said clock signal according to the converged second phase interval (S18).
