Equalization of the Distorted Chrominance Signal using IIR Digital Filter with the Bernstein Filter

Abstract

In this paper, we present the use of the Bernstein Polynomials to obtain an IIR digital filter transfer function, which can be applied to video equalizer for compensating the amplitude of chrominance signal in color television. In addition, experimental results are carried out by using the modulated 20T sine squared signal on the color sub carrier 4.43 MHz. It is shown here that the proposed equalizer can either enhance or compress the chrominance signal in color television transmission.

An IIR digital video equalizer design with the Bernstein Polynomial and generalized bilinear transformation for gain chrominance distortion

“…Prominent points obtained using the Bernstein Polynomial when compared to the Butterworth, Chebyshev and Thomson Polynomial are three parameters available control the amount of phase and magnitude, linear phase, and flexible for variable of phase [7][8]. In addition, a comparison of group delay can see that the generalized bilinear transformation is better than the bilinear transformation.…”
