Abstract

PURPOSE: To secure an easy and accurate display through the simple circuit by facilitating the phase detection through counting of the digital clock signals in the arc signal generating system through which the deflection signal to display the arc to the graphic display equipment.
CONSTITUTION: In the arc signal generating system to obtain the deflection signal which displays an arc to the graphic display equipment, clock generator circuit 5 to generate plural clock signals equivalent to the central angle information of the arc is installed along with 1st and 2nd sample holding circuits 6 and 7 which samples the X and Y deflection signals based on the clock signal of circuit 5 and holds these signals temporarily. In addition, the following units are provided: coefficient unit 8 and 9 to give attenuation of a fixed rate to the output of circuit 6 and 7; adder/subtractor circuit 10 to add the output of coefficient unit 9 and the output of circuit 6; adder/subtractor 11 to add the output of circuit 7 and the output of coefficient unit 8 together; and the circuit to feed back the output of circuit 10 and 11 to circuit 6 and 7 via switch circuit 12 and 13 respectively. And the X and Y direction signals passed through register 1 and 2 are suppied to circuit 12 and 13
