摘要：A gain controllable circuit suitable for processing vertical detail signal information in a video signal is disclosed. The circuit exhibits a non- linear signal amplitude transfer function wherein different amounts of signal gain are imparted to signals having amplitudes within prescribed ranges. Small amplitude signals subject to restoration are translated with a prescribed restoration gain. Moderate amplitude signals subject to enhancement (peaking), and large amplitude signals subject to paring (amplitude reduction), are controllably amplified without altering the restoration gain characteristic for small signals.
