I have problem in converting composite video signal to black and white signal. I used sallen key low pass active filter to remove color information. Its output is amplified, and fed to window comparator, its output are 1Vpk for white, 0.3Vpk for black, and 0V for sync pulses. When output is attached with TV, only large size objects are displayed correctly, small size objects aren’t displayed correctly, instead of small objects TV screen is completely white.
