Graphing fft in excel

Jul 01, 2019 · Usually a peak at 0Hz in the Frequency domain indicates the presence of a DC (Constant) bias in your time series data. If this were accelerometer data, it would indicate the presence of a static acceleration field influencing the sensors (gravity)... The plots in Figure 6 show the FFT magnitude responses for the rectangular, Hanning, and Hamming windows. I normalized the plots so the main-lobe peak for each curve starts at 0 dB, and the graph shows only positive frequencies. The graph for negative frequencies is simply a mirror image of this graph.
