<p>#CMT# #/CMT# The video corrector has program-controlled digital control circuit (36) and synchronous pulse output evaluation circuit (28) to which control inputs of impedance matching circuit (10), broadband amplifier circuit (14) and cascade equalizer circuit (18) are connected. The control circuit compares actual samples of digitized sync pulse of video signal with desired values by continuously changing control variables. #CMT# : #/CMT# An independent claim is included for method for adjusting video corrector. #CMT#USE : #/CMT# Video corrector. #CMT#ADVANTAGE : #/CMT# The video signal transmitted over different kinds of cables having different characteristic impedances and periodical damping measures can be corrected efficiently. The utilization efficiency of the video corrector can be improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of the video corrector. 10 : Impedance matching circuit 14 : Broadband amplifier circuit 18 : Cascade equalizer circuit 28 : Synchronous pulse output evaluation circuit 36 : Program-controlled digital control circuit.</p> |
