VIDEO SIGNAL PROCESSOR

In a television receiver, apparatus for non-linearly processing a vertical detail signal includes a plurality of cascaded amplifier stages 12, 14, 15, 16, 17 responsive to an input vertical detail signal and which exhibit linear and limiting operating regions. Vertical detail signals S2 and 23 from the amplifiers 15, 17 are translated 42, 43; 60, 62 and combined A with a linear version S1 of the input vertical detail signal. The combined vertical detail signal exhibits a characteristic output, Fig. 2, wherein small amplitude excursions within a first amplitude range I are cored, moderate amplitude range II are amplified with a given non-zero gain, and large amplitude excursions within a third amplitude range III are pared (attenuated).
