| Abstract: | This paper introduces the spectrum leakage phenomenon of DFT on the continuous signal spectrum analysis and analyzes the reasons for spectrum leakage. Then an adaptive synchronous sampling algorithm is presented. Using the frequency tracking technology, the algorithm may realize the sampling frequency adaptive adjustment. Simulation results show that the new algorithm can reduce the spectrum leakage availably. So the algorithm has a high value for application in the system based on AC measurement. |
