Abstract: |
An all-digital phase-locked arbitrary frequency multiplication algorithm based on FPGA is presented.Through analysis of the structure of the frequency multiplexing system,the realization principle and design method of the algorithm are given.A complete FPGA-based design example is provided.Simulation and experimental results show the algorithm is correct and realiable.Project applications prove the good performance of this algorithm. |
