Abstract

Two-dimensional recursive digital filters are widely used in signal processing and image processing, as well as divers communication systems. The main objective of this thesis has been to propose a new technique of designing 2-D recursive digital filters from an analog Bridged-T network. Starting from transfer function of a Bridged-T network in the analog domain which is VSHP, 2-D recursive digital filters can be obtained through the application of the double generalized bilinear transformations with the coefficients in their specified ranges. The impedance values of the transfer function of the Bridged-T network are obtained with compare to the fourth order Butterworth polynomial. For different impedance values of the Bridged-T network we get different types of filter output--all pass filter, band pass filter, band stop filter and low pass filter. The manner how each coefficient of generalized bilinear transformation affects each kind of 2-D recursive digital filter is investigated in details.
