Cathode-ray-tube raster line selector with horizontal modulation capability
Abstract
A simple and inexpensive circuit which provides a method of selecting the number and position of active raster lines visible on a CRT display is presented. Requiring inputs of vertical drive and horizontal and vertical sync signals, the circuits produces an output which can be fed directly into the video input of the display.
