Fast S.A.W.-based discrete Fourier transformer
Abstract
Combining SAW high-bandwidth filtering with digital data storage allows a digital DFT to be computed very rapidly though with limited accuracy. A prime algorithm processor is described, using a SAW filter interfaced with digital input/output, which dissociates the high but fixed speed of analogue computation from real data rates.
