Abstract: The present disclosure provides a method, device, and system for delaying signals as well as medical registration equipment, and belongs to the field of communication technologies. The method includes: determining, based on a clock period of each level of delay clock signals, a quantity of clock periods of each level of delay clock signals that are required for delaying a drive signal by a total quantity of delay phases; and delaying the drive signal by the determined quantity of clock periods of each level of delay clock signals sequentially. Therefore, on the premise that a data volume of a to-be-delayed drive signal is fixed, compared with a method for delaying signals by directly using a register, the method according to the present disclosure not only reliably realizes signal delaying, but also effectively reduces a quantity of required registers.
