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.
