Optical fft
WebThe optical IFFT/FFT circuits are usually comprised of an integrated passive optical network with several stages, each of which contains appropriate temporal delays and phase shifts. Many of these optical FFT circuits have special designs to simplify the circuit complexity [ … WebDec 1, 2024 · The first Fast Fourier transform (FFT) processing results show harmonic distortion on the frequency domain spectrum. To demodulate the acoustic frequency and amplitude information, twice-FFT processing is preformed. Experimental results reveal an accuracy up to 95.6% of acoustic signal in the frequency range 2–100 Hz.
