DIGITAL FILTER HAVING IMPROVED ATTENUATION CHARACTERISTICS

摘要

Disclosed is a digital filter having improved attenuation characteristics. The disclosed filter applies a sampling kernel which is scaled by a sampling constant to perform an upsampling process for a model filter response. The disclosed filter is advantageous in that it has a smaller number of taps and excellent attenuation characteristics, and is capable of changing the pass band of the filter by simply changing a parameter.
