Picture Signal Improvement (PSI) circuit

GENERAL DESCRIPTION\nThe TDA4671 delays the luminance signal and improves colour-difference signal transients. The luminance signal\ncan also be improved by peaking and noise reduction (coring).FEATURES\n• Luminance signal delay from 20 to 1100 ns (minimum step 45 ns)\n• Luminance signal peaking wit • Luminance signal delay from 20 to 1100 ns (minimum step 45 ns)\n• Luminance signal peaking with symmetrical overshoots selectable\n• Selectable 2.6 or 5 MHz peaking centre frequency and degree of peaking (−3, 0, +3 and +6 dB)\n• Selectable noise reduction by coring\n• Handles negative as well as p;
