Abstract
A thermometer or bouncing-ball LED display system provides a fast response, easily readable, quantitative indication of a variable. A received analog signal, representing the variable to be displayed, is effectively compared with an analog signal representing the present display indication. The difference therebetween is averaged over a sampling period. If this average difference exceeds a predetermined limit in either a positive or negative direction, the display indication is changed to reflect this difference. The sensitivity of the display can be selectively determined by increasing or decreasing the sampling frequency and the predetermined limit. The display system can be selectively operated in three different response modes. In a fast-attack, slow-release mode, the display indication is changed more rapidly in response to positive direction differences in the compare stage, than in response to negative direction differences. In a fast mode, the display indication is changed rapidly in response to either positive or negative direction differences in the compare stage. In a slow mode, the display indication is changed less rapidly in response to either positive or negative differences in the compare stage.
