Step 1: Enter Data
Step 2: Fourier Analysis
Enter up to 100 numbers below, and I will calculate the Fourier Series.
(If you need to calculate a Fourier Series for more than 100 data values, please try my DownloadGT AddIn for Microsoft Excel.)
This calculator turns your data into a Mathematical formula by generating a Fourier Series of sines and cosines.  You can then use this formula to make predictions, and also to find repeating patterns within your data.  To begin, enter your numeric data into the textbox on the left, and then click on the "Next" button below to perform the calculation of the Fourier Series.
