摘要：

Combining s.a.w. high-bandwidth filtering with digital data storage allows a digital d.f.t. to be computed very rapidly though with limited accuracy. A prime algorithm processor is described, using a s.a.w. filter interfaced with digital input/output, which dissociates the high but fixed speed of analogue computation from real data rates. © 1978, Controller, HMSO.
