definition from 2nd Edition, McGraw Hill Dictionary of Scientific and Technical Terms: "dynamic range (electrical engineering) - the ratio of the maximum signal level capacity of a system or component to its noise level, usually specified as decibels." capacity, not what happens during use. no time. imaging sensors capture all of their signal simultaneously. what's the maximum possible, what's the minimum possible, and what's the difference.
