ABSTRACT:
A liquid crystal display has a first system of parallel elongated electrodes and a second system of parallel elongated electrodes. The first and second systems are perpendicular to each other. The electrodes in the second system are biased in such a fashion that each electrode in the second system has a greater bias voltage than has the next electrode in the second system. An analog multiplexer connects an analog input signal to all of the electrodes in the first system in a sequential fashion of repeated sweeps. The signal is displayed on the liquid crystal display in a histogram-like format of signal strength versus time.
