Algorithms for block filtering with hardware FFT processors
DJ McLean, JD O'Sullivan, CE Jacka, W.P. Stroud · 1st IASTED International Symposium on Signal Processing and its Applications · 1987
The Fast Fourier Transform (FFT) is a familiar tool in signal processing applications such as filtering. The availabihty of a pipehned FFT chip (O'SuUivan et al, this conference) makes it possible to build specialised hardware processors to perform filtering operations on high speed streams of data.
