Proceedings. 1998 IEEE International Conference on Information Technology Applications in Biomedicine, ITAB '98 (Cat. No.98EX188), 2002 This paper presents a high performance frequency domain filter implementation for a moving window-type processing. The computational structure consists of three stages: a sliding discrete Fourier transform (SDFT) for a vectorized updating of the DFT; a frequency domain filter; and a one-point inverse discrete Fourier transform (IDFT).

IEEE Transactions on Power Electronics, 2005 Line synchronization of grid connected power converters is a well recognized problem when the grid is weak, or derives from a remote area power supply with poor frequency regulation. Such systems can suffer significant line voltage distortion due to notches caused by power device switching and/or low frequency harmonic content, which can easily corrupt

High-resolution spectral analysis (HSA) vs. discrete fourier transform (DFT)
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2021The Discrete Fourier Transform (DFT) is the standard technique for performing spectral analysis. It is used in the form of the well-known fast implementation (FFT) in almost all areas that deal with signal processing. However, the DFT algorithm has some limitations in terms of its resolution in time and frequency: the higher the time resolution, the ...

ABSTRACT In this paper, a spiral systolic array (SA) architecture with asynchronous controls forthe real time realization of an N point DFT and [DFT is considered. The study includes theoverall system block diagram, propagation of data between array PEs, operations withineach PE, and the PE protocol for computing an N point DFT.

Fourier Transform Analysis of Discrete Time Signals and Systems—DTFT, DFT and FFT
2021In Chap. 4, we represented continuous time periodic signals as a sum of everlasting exponentials by Fourier series. Similarly, in Chap. 5, the discrete time periodic signals was represented by discrete time Fourier series using a parallel development of continuous time system.
