Real-time Fft Algorithm Applied to On-line Spectral Analysis*

Abstract

On-Iine running spectral analysis is of considerable interest in many electrophysiological signals, such as the EEG (electroencephalograph). This paper presents a new method of implementing the fast Fourier transform (PTT) algorithm. Our "real-time FFT algorithm" efficiently utilizes computer time to perform the FFT computation while data acquisition… (More)
