Abstract
Abstract An electronic system for computing the integrals of various fractions of the time varying electrical output of a scanning densitometer provides that output to a graphic recorder, an analog-to-digital converter and to a slope detector which generates signals representing the boundaries of various fractions of the signal. This detector output is also provided to the recorder to produce a curve representing the amplitude variations of a densitometer signal with marks at the boundaries. The outputs of the analog to digital converter and the slope detector are provided to a shift register. An operator generates correction signals based on an observation of the recorder trace representing desired changes in the boundaries as determined by the slope detector. The densitometer output of the shift register is integrated over time periods controlled by the boundary output of the shift register as manually corrected.
