| Abstract: | The method and engineering application of alternating sampling are investigated by using Fourier algorithm,and caculatin algorithm of a type of alternating sampling is suggseted by using two meters.A new method of alternating data acquisition by A/D transformer and a modulating and filter circuit used for current and voltage signal are introducde ,and the function for alternating sampling calculation is deduced.The programming method of alternating sampling by C language is described.It has been proved that the circuitand algorithm are correct as well as submitted for alternating data acquisition in power system and other industrial control system. |
