Abstract

A method and a configuration are provided for digitally processing an analog signal, especially of output quantities of an optical transducer. The analog signal is divided into a number of partial analog signals having in each case different frequency ranges. The levels of the partial signals are adapted to the dynamic ranges of downstream digitizing device by analog amplification. This results in an improved signal-to-noise ratio.
