An Adaptive Computer-Controlled Digital Filter -- An Application of the Hewlett-Packard 5470A Fourier Processor.
Abstract
One-stage digital filters are described mathematically. An expression for average power gain over a frequency interval is derived. Anti-bias, anti-alias and band-pass filters are presented as examples. Microprograms to implement such filters on a Hewlett-Packard 5470A Fast Fourier Processor are presented together with a timing table. The facility so described enables a user to filter adaptively under computer control.
