Apparatus and method for detecting when a measured variable represented by a string of digital pulses reaches a plateau

摘要: A method for detecting a plateau measured variable by comparing the clock pulses from dual slope analog to digital converter which are counted during consecutive pairs of conversions. The counter is decremented first conversion and incremented second. If counts detected as being identical within prescribed number an accumulator incremented. predetermined successive increments indicates plateau. cleared whenever pair conversions not window.
