Piezoelectric Energy Harvesting
Fast Fourier Transform (FFT) is an efficient algorithm that computes the discrete Fourier transform (DFT) and its inverse. This mathematical process transforms a signal from its original domain (often time or space) into the frequency domain, enabling analysis of the signal's frequency components. FFT is crucial for adaptive impedance matching, as it helps in analyzing and optimizing the performance of energy harvesting systems under varying conditions.
