| Abstract: | A feedback algorithm based on digital correlation method is investigated,and it works at relatively low sampling frequency to solve multi-channel MUXDAC synchronizing problem.The principle and implementation method of the algorithm are analyzed.The influences of the parameters on accuracy are also analyzed.The algorithm has been used in a multi-channel radar AWG system,and it has been vesified that the algorithm can be implemented easily and improves the reliability of the whole system. |
