Abstract
A new kind of oscilloscope is proposed and realized. The oscilloscope named the graphic oscilloscope is capable of displaying graphic patterns whose shapes and positions can be changed by analog inputs.
This system generates, by its analog circuits, more than ten kinds of basic characters such as a circle, a triangle, a line vector and so on. More complex patterns are synthesized by combining the basic characters under the control of a microprocessor.
Two application examples, a two-channel analog CRT meter and a face pattern display are illustrated. They give us satisfactory results showing the basic functions of the graphic oscilloscope.
