Abstract

PURPOSE:To display polar coordinates on a Braun tube by simple circuit constitution, by extracting signals each corresponding to distance up to a marker location from the center of spiral one cycle sweep and declination. CONSTITUTION:After keying pulses a are generated at a location on a Braun tube decided by the positional marker set voltage Vx, Vy of each deflection set circuits 3, 4 of an X axis and a Y axis, pulses h are emittd from an AND11 when spiral one cycle sweep comes. Distance pulses i are counted by means of a distance counter 12 after counting value is reset by the pulses a, and the counting value R is extracted by means of a latch circuit 14 at the same time as the detection of the pulses h. Angle pulses k are counted by means of a directional counter circuit 13 after counting value is reset by directional reference pulses j sent out every one revolution of spiral one cycle sweep, the counting value theta is extracted by means of a latch circuit 15 at the same time as the detection of the pulses h, and distance R is displayed to a distance display portion 16 and declination theta to a directional display portion 17 respectively.
