2-D FIR filters design using least square error with scaling-freeMcClellan transformation

摘要

The optimal coefficients of the scaling-free McClellanntransformation and the 1-D prototype filters for the design of 2-Dndigital filters are designed in this brief. These 2-D filters includenfan filters with arbitrary inclination, elliptically symmetric filters,nelliptically symmetric filters with arbitrary orientation, circularnfilters and diamond-shaped filters
