Claim Text:
1. A method for processing a measured-value signal detected by a sensor and determined in an analog manner, comprising: supplying the measured-value signal to a delta-sigma modulator, which makes a bit stream available on an output side; supplying the bit stream to a first digital filter, the first digital filter having a number n of serially arranged accumulators, n being a whole number and equal to at least 1; converting the bit stream, by the first digital filter, into an intermediate data-word stream of digital intermediate words, the bit stream being clocked at a clock-pulse frequency fS and a clock-pulse period TS=1/fS, and the stream of digital intermediate words being clocked and updated at a clock-pulse frequency fS and a clock-pulse period TS=1/fS; supplying an output signal of first digital filter to a second digital filter, the second digital filter having a difference between a first and a second result data-word stream as an output data-word stream, the first and second result data-word stream being determined over a first and second time interval from the intermediate data-word stream, the first and second time interval being situated at a distance in time T
