Abstract
A signal receiver having a source of video signals includes an aperture correction system wherein an electron device coupled to the video signal source provides first and second oppositely-phased output signals which are applied to a circuit means to be differentiated and delayed respectively and applied to a summing terminal with desired preshoot and overshoot characteristics. Moreover, these characteristics are selectable by an adjustable impedance coupled to the circuit means providing the differentiated and delayed signals.
