Clock frequency modulation method and clock frequency modulation apparatus |
摘要 |
Embodiments of the present invention provide a clock frequency modulation method and a clock frequency modulation apparatus. The method includes: determining N digital clocks according to a first digital clock of a system, where the N digital clocks includes a second digital clock and N-1 digital clocks except the second digital clock, and a sum of frequency ratios of the first digital clock to each of the N-1 digital clocks is equal to N-1 times a frequency ratio of the first digital clock to the second digital clock, where N is an integer greater than 2; and fitting, during a modulation period by using the N digital clocks, the first digital clock into the periodic second digital clock. The embodiments of the present invention use a clock frequency modulation technology to make energy concentrated in a frequency spread to a wider frequency range. |

1. A clock frequency modulation method, comprising:
determining, by a clock frequency modulation apparatus, N digital clocks according to a first digital clock of a system, wherein the N digital clocks comprise a second digital clock and N-1 digital clocks except the second digital clock, and a sum of frequency ratios of the first digital clock and each of the N-1 digital clocks is equal to N-1 times a frequency ratio of the first and second digital clocks, wherein N is an integer greater than 2, and wherein each of the N digital clocks is an integer frequency dividing clock of the first digital clock and frequency dividing coefficients of the N digital clocks are different from each other; and fitting, by the apparatus, the first digital clock into the second digital clock during a modulation period using the N digital clocks. |
