Design of Linear Phase, Finite Impulse Response, Two-Dimensional, Digital Filters
D.F. Ciccolella · Defense Technical Information Center (DTIC) · 1980
An interactive computer program was developed that enables the user to design linear phase, finite impulse response, linear shift-invariant, two-dimensional digital filters. The program user can design lowpass, highpass, bandpass, bandstop, all-pass, and multiband two-dimensional digital filters. The filters designed by using the program are nearly optimal in the Chebyshev sense. The technique implemented in the program consists of transforming a one-dimensional digital filter into a two-dimensional digital filter by a change of variables. This technique was first proposed by James H. McClellan and is called the McClellan Transformation. The program user can elect to utilize either the first order or the second order McClellan Transformation to design a two-dimensional digital filter.
