hi,
can anyone guide me on how to convert the data to fft. the reason i use fft is to find the harmonics in the data as the data represents leakage current from a surge arrestor. i need to find 1st,3rd,5th and 7th harmonic. please do suggest if there is any other method to find the harmonics in the data. the harmonics need to be plot out as a graph. attache is the vi and also the data file.
thanks
