NON-LINEAR PROCESSOR FOR VIDEO SIGNAL VERTICAL DETAIL COMPONENT |
摘要 |
<p>RCA 76,978 In a television receiver, apparatus for non-linearly processing a vertical detail signal includes a plurality of cascaded amplifier stages responsive to an input vertical detail signal and which exhibit linear and limiting operating regions. Vertical detail signals from the amplifiers are translated and combined with a linear version of the input vertical detail signal. The combined vertical detail signal exhibits a characteristic wherein small amplitude excursions within a first amplitude range are cored, moderate amplitude excursions within a second amplitude range are amplified with a given non-zero gain, and large amplitude excursions within a third amplitude range are pared (attenuated).</p> |
