ABSTRACT:
A cathode-ray oscilloscope controlled by a circuitry receiving four (4) voltage inputs representative of the Cartesian coordinates of endpoints of two (2) vectors, for visually displaying the vectors in the form of a dashed line segment and a solid line segment. The circuity responds to operator input for generating display signals to rotate the two displayed vectors with respect to the CRT screen and responds to internal control for blinking the display of either of the vectors according to a preset vector magnitude limit.
