ABSTRACT:
An apparatus is disclosed for displaying arbitrary forms on a raster-scanned cathode ray tube converting the analog X and Y deflection voltages of the raster signal directly into a digital TTL level blanking signal. The circuit designer, utilizing cartesian or polar coordinates, specifies a desired shape and its location utilizing the appropriate formulas. In this manner, a number of raster cut-out circuits are readily coupled to define a desired number of arbitrary shapes on a raster scanned cathode ray tube.
