A graphical animation authoring system for in-class demonstration of circuit operation

Abstract

A graphical animation authoring system has been developed which makes it possible for the course instructor to add text, arrows, lines, blocks, and waveforms to textbook schematic diagrams. Moving cursors on the waveforms and varying lengths of the arrows or VU meter displays emphasize the source and resulting response nature of the circuit operation. Standard overhead projector transparencies are used with a liquid-crystal-display unit attached to a portable PC for in-class presentations. The displayed information is organized as frames within each page, so that successively more complex pictorials can be revealed in succession for each page. The resulting displays are used to aid visualization of circuit operation. Some animation examples are given.<>
