Abstract
Related multiple characteristics of a single complex waveform are displayed as a variable length line of light with a floating spot which moves relative to the line. Logic circuitry, in response to an electrical input signal, causes energization of a plurality of the light emitters in response to the first input signal characteristic and the energization or extinguishing of a single light emitter in response to a second characteristic of the input signal.
