METHOD AND DEVICE FOR DIGITIZING AN ANALOG ELECTRICAL SIGNAL AND METHOD FOR DIGITIZING

摘要

The invention relates to a method and a device for digitizing an analog electrical signal (Sa), in which the signal (Sa) is applied to a number of subchannels (SK1, SK2, SK3) connected in parallel, in which the amplitude ranges (AB1, AB2, AB3) of immediately adjacent subchannels (AB1, AB2, AB3) with respect to amplitude are in each case displaced overlapping one another, in which the overlapping amplitude ranges (AB1, AB2, AB3) comprise the predetermined total amplitude range (D) , in which a subchannel (SK3) serves as reference channel, in which, on the basis of the reference channel, the digital output value of the immediately adjacent subchannel (SK1 or SK2, resp.) with respect to amplitude is corrected when the signal (Sa) is in the overlap range of the two subchannels (SK1, SK2 or SK2, SK3, resp.) and the digital values differ from one another, and in which a total digital value is output by means of a digital output value, taking into consideration the displacements (V) of the amplitude ranges (AB1, AB2, AB3) with respect to one another.
