Frequency Domain Using Excel - Tao Xing
San Francisco State University School of Engineering Frequency Domain Using Excel by Larry Klingenberg April 2005 Introduction: Waveforms plotted in Excel generally show the magnitude (Y-axis) versus time (X-axis). (See Figure 1, Data in Time Domain .) Knowing the period T of the waveform, the Frequency can be calculated. Amplitude vs Frequency324 Hz02040608010012014005001000150020002500 Frequency (Hz)amplitudeFigure 2: Data in Frequency DomainFigure 1: Data in Time ms-150-100-50050100150202122232425262728 2930 Time (ms)Amplitude (units) Frequency =324 Hzperiod = ms Sometimes experiments call for the harmonic content of a reproduced waveform. The harmonic content is a display of the magnitude of the waveform (Y-axis) versus the Frequency (X-axis).
