This is a Python demo used to understand the concepts of FFT (Fast Fourier Transform), animation, and how they all tie together. The script performs FFT analysis on either WAV files or captured audio ...

Performance Ratio (PR) is a critical metric for evaluating the performance of Photovoltaic (PV) power plants. PR values are influenced by various factors, with some being weather-dependent, which ...

Abstract: When the fast Fourier transform (FFT) algorithm is used to analyze demodulate interference signal, nonsynchronous sampling of the interference optical spectrum would cause spectral leakage ...
