Fast Fourier Transform (FFT) (Part 2)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 Here is a recap of the pieces of code that we need in order to convert a wave into a frequency spectrum: Store data in a vector (Double data type) Weigh this data according to one function (default is Rectangle, also known as box car, in other words, no weighing!) Execute the FFT algorithm […]
