<p>A measurement unit, in partic. a modulation measurement device for multichannel electroacoustic arrangements with a display unit cont. light elements indicating parameter values by the length of the element which is illuminated, enables easy indicator reading, and is economical even for non-linear indication. It may be installed in any position. The light elements are cyclically illuminated, and to provide scale marking individual light elements are illuminated during different periods from the remaining light elements. The illumination signals are derived from a time generator and a processing circuit contg. switches, a pulse shaper, comparators and counters.</p> |
