Symmetry Incorporated Cost-Effective Architectures for Two-Dimensional Digital Filters
IEEE Circuits and Systems Magazine(2019)
Abstract
Professor Fettweis as far back as 1977 published a paper generalizing McClellan transformation to obtain circular symmetry in 2-D and spherical, hyper-spherical symmetries in multidimensional digital filters [1]. This survey paper presents stateof-the-art two-dimensional (2-D) VLSI digital filter architectures possessing various symmetries in the filter magnitude response. Preceding the symmetry s...
