Fast Fourier Transform (FFT) (Part 10)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 Now that we know how to get nice, clean frequency spectra comes the time for extracting valuable information. For this pupose, I added a couple of DSP functions to the (now very popular) PlainFFT library. As we will deal with peaks, I created a dedicated variable which will be update by these functions: typedef […]
