    摘要： A current distribution circuit suitable for use in a digital-toanalog converter in which digital signals are applied either directly or through a logic network to selected flip-flop stages such that the flip-flops produce a number of output signals which individually represent a given increment of current. These current increments are made available to a resistive ladder type current metering circuit to produce the desired analog voltage.

    摘要： A character generator for a cathode-ray tube display system including the capability of digitally generating curved characters. Each diode matrix used for generating a character produces output signals in digital form representing the Xcoordinate, the Y-coordinate, the intensity of the particular stroke of the character being drawn, the degree of departure of the stroke from a straight line if it is to be curved and the direction in which it is to be curved.
