Electron-Beam Spot Characteristics and Video-Circuit Characteristics

The authors discuss how to determine the video-circuit characteristics in order to improve picture sharpness of color TV sets. In particular, they tried to obtain such characteristics that would maintain good picture sharpness by preventing “blooming” phenomena, which the beam spot characteristics of the color picture tube would present at high beam current level. This paper concludes that it will be advantageous to reduce the shoot-height and widen the shoot-width in transient response of the video circuit, if attention is paid particularly to the sharpness at a high peak, which is an important factor of picture quality.
