Abstract
A signal peaking device for a single line video input has a transversal filter with a plurality of sample and hold (S & H) circuits, a corresponding plurality of line drivers and output switches. The output switches are connected to a plurality of weighting circuits and a summer that sums the weighted output of the output switches. A free running digital shift register generates the sample pulse that operates the sample and hold circuits.
