“…In 2-D filters, stability cannot be ensured when one applies the bilinear transformation to the analog filters, because of the possible presence of non-essential singularities of the secondkind. This can be overcome by generating Very Strict Hurwitz Polynomial (VSHP) in the 2-D analog domain [1,2] and then applying the generalized bilinear transformations [3].…”

This paper proposes a new technique of designing 2-D recursive digital filters starting from a doubly-terminated analog Bridged-T network. This network contains inductive and capacitive reactance elements in s 1 and s 2 domains. The different possibilities are examined . When compared with the fourth order Butterworth polynomial, only three possibilities exist and the corresponding impedances are obtained. Starting with such an analog Bridged-T network, 2-D filters are obtained through the application of double generalized bilinear transformations with the coefficients in the specified ranges to ensure stability. Different filter outputs can be obtained, depending on the starting network and the coefficients of the generalized bilinear transformations.

Video equalizer design for compensated the distortion of the chrominance amplitude in color television transmission system is presented. The approximation is based on the Bernstein Polynomials and generalized bilinear transformation to obtain the transfer function. This approach has several parameters can be varied satisfying stability conditions. And the advantages of the Bernstein Polynomials when compared to the Butterworth, Chebyshev and Thomson Polynomials are three parameters available control the amount of phase and magnitude, linear phase, and flexible for variable of phase. Among all referred advantages so that these methodologies were applied in this paper. In addition, the pulse and bar test signal which has been used to measure linear waveform distortion in TV system is special the modulated 20T sine squared pulse with color sub-carrier 4.43 MHz for PAL system. As a result, the proposed digital video equalizer can be enhance and compress the gain chrominance distortion without degraded it phase characteristic.
