Abstract
A method and apparatus for high-resolution digitization of a signal with a large dynamic range employ an analog-to-digital converter having a bit number and having a measuring region which is smaller than the total range of measurement of the incoming signal, the range of measurement being divided into smaller measuring segments which partically overlap, each measuring segment having a size corresponding to the measuring ranges of the analog-to-digital converter. The information from the analog-to-digital converter controls a measurement segment selector such that the signal to be converted into digital form is within the selected segment. A new digital signal value is extrapolated at least from the two last bits from the analog-to-digital converter.
