Calculating Harmonic Amplitude and Phase Angle of Signals Using FFT

Using FFT (Fast Fourier Transform) to compute amplitude and phase angles of harmonic components in signals, with code implementation details.

Power Grid Harmonic Analysis Using Hamming Window Interpolation for Calculating Harmonic Frequency, Amplitude, and Phase Angle

Power grid harmonic analysis employing Hamming window interpolation for precise calculation of harmonic frequency, amplitude, and phase angle. This method is built upon Fast Fourier Transform (FFT) fundamentals and incorporates advanced interpolation techniques to enhance measurement accuracy beyond standard FFT implementations. The algorithm effectively reduces spectral leakage through windowing functions while improving frequency resolution through polynomial interpolation between FFT bins.
