1. A method for delaying signals, wherein the method comprises:
determining a total quantity of delay phases by which a drive signal is to be delayed;
determining, based on a clock period of each level of delay clock signals of a plurality of levels of delay clock signals, a quantity of clock periods of each level of delay clock signals that are required for delaying by the total quantity of delay phases, wherein the clock periods of the levels of delay clock signals decrease sequentially from a first level to a last level; and
delaying the drive signal by the quantities of clock periods of the levels of delay clock signals sequentially in descending order, and outputting the drive signal after delay.
