The graph displays the dominant frequencies as peaks.US20090132347A1 - Systems And Methods For Aggregating And Utilizing Retail Transaction Records At The Customer Level This time, drag the equation only to the halfway point in the column.Ĭreate a graph, using the FTT Magnitude column for the y-axis and the FTT Frequency column for the x-axis. Create a separate cell with the equation "=(S/2)/(N/2)," replacing "S" with the sampling rate and "N" with the number of samples.Įnter the equation "=F2*SG$4" in the first cell of the FTT Frequency column. This equation creates real numbers, instead of complex numbers, in the previous column.įill column F with the corresponding data, from column A, point minus one. Drag the equation downward to fill every cell of the column. Type the equation "=IMABS (E2)" into the first cell of the FTT Magnitude column. Set the input range as the information in the Data column and the output as the FFT Complex column. Open the "Data" tab, and then select "Data Analysis." Select the "Fourier Analysis" option and press the "OK" button.
