Abstract: A signal processing method and apparatus. According to the signal processing method, phase change processing can be performed on to-be-sent data signals according to a phase status of a data synchronization signal and phase statuses of the to-be-sent data signals, so that phase differences between a majority of to-be-sent data signals in the processed to-be-sent data signals and the data synchronization signal meet a certain condition, thereby reducing a volume of coupling crosstalk, generated by the to-be-sent data signals, on the data synchronization signal and further reducing impact of simultaneously switching noise (SSN) on a system.

Abstract: A power management method includes power sourcing equipment (PSE) supplying power to a plurality of powered devices (PDs), and determining reserved power of the PSE based on a power usage status, where the reserved power is used to continue supplying power to the plurality of PDs when actual available power of the PSE is exhausted, and where the reserved power varies with the power usage status of the PSE.
