Abstract
A directivity display device and method are disclosed which involve a first saw-tooth generator producing a scan signal and a brilliance modulation circuit producing a brilliance modulated signal derived from the characteristic output of a test object with respect to a rotational angle of the test object. Thereby, the directivity display device makes it possible to display in graphic form a property of the test on a cathode-ray tube with a polar or other coordinate representation.
