Hi, example: I have two series: t=Table[tt,{tt,0,10,0.01}]; x=Table[Sin [A t],{t,0,10,0.01}]; I expected maximum peak on frequence Omega=A ( omega = 2 Pi/T, not 1/T) It must be independece on density (0.01) and length (10) I need that to analyse of solution differential equation that look like a chaotic. regards, Olaf
