Hi all,

I obtained amplitude vs frequency of my signal. After plotting the fft I want to calculate the energy of specific bands (The integral of the area under the curve.) But FFT is discrete.. Also when I zoom in specific frequency for ins 50 Hz, I see a curve as it was continuous. That confused me. How can I calculate the energy? Does someone have any idea?
