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 four samples of the digital signal. A correction is generated as a function of the four samples, and a filtered sample is generated by modifying the approximate filtered sample with the correction.
