    摘要： A capacitance sensor, having at least one electrode is disclosed. A frequency spread signal generation circuit is coupled to the at least one electrode to apply a frequency spread signal based on a spread sequence. A periodic signal with a frequency is coupled to the at least one electrode. A frequency controller is coupled to the frequency spread signal generation circuit to vary the frequency of the periodic signal. A receiver circuit is coupled to the at least one or a further electrode to receive a version of the frequency spread signal which depends on a capacitance applied to the at least one electrode. An evaluation circuit is coupled to the receiver circuit to determine a capacitance value based on the received, dependent version of the frequency spread signal.

    摘要： In a measurement method, an array of magnetic field sensors (MS0-MS15) is provided, each emitting a sensor signal as a function of magnetic field intensity. A rotational value of a sector-wise magnetized magnetic source that is arranged movably with respect to the array is ascertained as a function of the emitted sensor signals. A set of sensor values is derived from the sensor signals. As a function of the ascertained rotational value, a number of sets of reference values is ascertained that corresponds to a number of predetermined positions of the magnetic source (MAG). The set of sensor values and the number of sets of reference values are compared to one another, and a position is selected from the number of predetermined positions as a function of the comparison.
