  • Patent number: 4117473
    Abstract: A horizontally oriented curve is produced on a raster type cathode ray tube display by storing curve data words in a memory and placing a series of dots on the cathode ray tube screen with each dot being at a height dictated by the value of the respective data word and at a horizontal position dependent on the order in which the respective data word is received. A dot counter provides an output signal for writing the curve data words into the address locations of the memory in the order in which the curve data words are received. A horizontal raster position counter provides a read address signal to the memory for each possible dot position in a horizontal scan. A comparator circuit compares each curve data word read out of the memory with a signal representative of the vertical position of the current horizontal scan and produces a video enable signal to produce a dot on the cathode ray tube screen when the compared signals are equal.
