This paper presents a linear luminance-chrominance gain equalizer for compensating the linear chrominance gain distortion in color TV transmission system. The proposed equalizer was implemented based on Bernstein polynomials. As it is known, the Bernstein type filter has flexible parameters to adjust the circuit performance for the best results. In addition, the modulated 20T sine-squared pulse test signal is generated for testing the proposed equalizer, which can be measured all three types of the linear distortion. As the results, the proposed equalizer is also proved to be efficient in equalizing both the low gain and the high gain chrominance distortions without degraded it phase characteristics.
