Fast Fourier Transform (FFT) (Part 11)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 Here is an other peak related DSP function. The purpose of this one is to get the peak information of a targeted frequency peak. It uses the same early steps as in the MajorPeak function. The filtering process includes a peak interpolation (quadratic type), and the calculated peak apex position is compared to the target […]
