Abstract : A raster generator for producing a raster-type display on a random scan display terminal where the raster can be oriented at any selected angle of rotation. The rotating raster generator responds to a digital input signal representing the desired angle of rotation which may represent, for example, the turning or rolling motion of a vehicle. The generator operates digitally to provide an output comprised of two sets of digital signals, each signal set representing an axis rotated in an amount directly related to the value of the input angle. The signals are presented as inputs to the deflection coils of a cathode-ray tube (CRT) or like display.
