The Parameter Determination in the Design of 3-D Spherically Symmetric FIR Filters via the McClellan Transformation

摘要

In the design of 3-D spherically symmetric FIR filters via the McCiellan transformation, twomethods are proposed to determine the transformation parameters. The first is to improve the original 3-Dalgorithm by exploiting the 2-D effective methods in 3-D. This method can change the constrained optimization algorithm into the unconstrained one and makes the design easier to realize. The second method is tosolve the coupled equations under constrained conditions and a set of ideal parameters can be gotten. The design example shows that the two methods are all efficient and easier than the original algorithm.
