Abstract: A vertical aperture equalizer employing delays of one scanning line has been built and has been used on commercial broadcasts to increase the subjective sharpness of television pictures. By using both vertical and horizontal aperture equalization, optical aperture defects can be corrected. By the use of vertical aperture equalization and scanning apertures with suitable responses, television in the future may be practically free of line structure and spurious pattern effects due to the scanning-line structure.
