Abstract
A display system for providing a real-time, dynamic presentation of an analog signal waveform is disclosed. The system includes an A-D converter that, in turn, drives a serial string of binary weighted bubble domain generators. The bubble domain generators generate moving columns of bubble domains, the total amplitude of light that is provided by each column representing the amplitude of the analog signal waveform at each of an associated sample time. The bubble domain memory plane is of a construction to permit the columns of moving bubbles to appear as moving columns of bright spots when seen by an observer using a plane polarized light beam and an analyzer.
