Title:
METHODS AND SYSTEMS FOR EFFICIENT FILTERING OF DIGITAL SIGNALS
Document Type and Number:
WIPO Patent Application WO2003063351
Kind Code:
A3
Abstract:
A method in a signal processor for filtering samples in a digital signal is provided. An approximate filtered sample is generated as a function of less than four samples of the digital signal. A correction is generated as a function of the less than four samples, and a filtered sample is generated by modifying the approximate filtered sample with the correction.
