A high performance continuous data flow filter using sliding discrete Fourier transform (DFT) and one point inverse DFT

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).

Measurement of time delay using the time shift property of the discrete Fourier transform (DFT)

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1986
The time shift property of the discrete Fourier transform (DFT) is used in the measurement of time delay. The eccentricity of a screw rod has been experimentally measured, and delays of the ultrasonic wave have been known with the precision of one percent of the temporal sampling interval.
