Fast Fourier Transform Tutorial Fast Fourier Transform (FFT) is a tool to decompose any deterministic or non-deterministic signal into its constituent frequencies,
FFT Tutorial
Calculate the FFT magnitude (column D) by finding the absolute value of the FFT complex of column E and multiply it by 2/sa In our example, sa=1024 Place the cursor in cell D2 and use the formula bar to enter the following formula: =2/1024 * IMABS(E2)
