## In this work a modtjication of a scheme developed previously is presented. The technique uses the McClellan transformation applied to a 1-D zero-phase recursive jlter to obtain a 2-D zero-phase recursive jlter which is unstable. The stabilization process is done through the decomposition of the 2

An analytical technique is developed for designing multidimensional (M-D) separable-denominator recursive digital,filters that meet, simultaneously, magnitude andphase spec$cations. A cubic symmetry that exists in the M-D .frequency response is incorporated into the M-D,filter structure. The denomin
A computationall\_v eficient technique is developed for the design of twodimensional (2-D) recursive digital jilters that meet simultaneously magnitude and phase specifications. A quadrantal symmetry which exists in the 2-D frequency response is incorporated into the 2-D jilter design. The denominat
## Abstract The new phaseβshifter configuration described in this report uses a negative group delay (NGD) active circuit. In this topology, a classical transmission line is set in cascade with an NGD circuit whose phase slopes are alike, but opposite, to get a constant and broadband phase shift. T
