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 is coupled to a 1-out-of-M decoder that, in turn, drives a serial string of bubble domain generators. The bubble domain generators generate moving columns of bubbles, the heights of the columns representing the amplitudes of the analog signal waveform at each of the associated sample times. 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 utilizing a plane polarized light beam and an analyzer.
