  • Patent number: 10735022
    Abstract: In method for processing a measured-value signal determined in an analog manner and a resolver system for implementing the method, the measured-value signal being supplied to a delta-sigma modulator, which makes a bit stream, particularly a one-bit data stream, available on the output side, in particular, whose moving average corresponds to the measured-value signal, the bit stream being supplied to a first digital filter, which converts the bit stream into a stream of digital intermediate words, that is a multibit data stream, the first digital filter having three serially arranged differentiators, the bit stream being clocked at a clock frequency fS, that is, at a clock-pulse period TS=1/fS, and therefore the stream of digital intermediate words being clocked, and thus updated, at a clock-pulse frequency fD, that is, at a clock-pulse period TD=1/fD, the output signal of the first digital filter being supplied to a second digital filter, the second digital filter having as its output data-word stream the dif

  • Patent number: 10135458
    Abstract: A method for processing a measured-value signal representing a value, determined in analog form, for the output current of a converter, and device for carrying out the method, the measured-value signals acquired by a sensor, especially including a shunt resistor, being supplied to a respective processing channel that has at least one delta-sigma modulator.
