    摘要： A phase locked loop (PLL) circuit includes a first signal detector having a first input terminal configured to receive a varying first input signal, a second input terminal configured to receive a feedback signal that corresponds to the center of the input frequency, and an output terminal configured to provide an output signal corresponding to a phase difference between the first input and feedback signals. A delay estimator has an input terminal configured to receive the output signal from the first phase detector and in response thereto, output a phase difference estimation signal. A variable delay circuit has an input terminal configured to receive the phase difference estimation signal and in response thereto, phase shift the second input signal.

    摘要： A method for evaluating a sensor signal provided by a magnetic field sensor which is arranged at a distance from an object which is rotatable about an axis of rotation is disclosed. The method includes defining an encoding pattern with a sequence of symbols, the sensor signal being dependent on the encoding pattern and at least one transmission parameter; regenerating the symbols of the encoding pattern from a corrected sensor signal using a threshold value detector to obtain an output signal; generating a filtered signal from the output signal using a filter having a plurality of filter coefficients; superposing the sensor signal and the filtered signal to obtain the corrected sensor signal; and wherein the corrected sensor signal and the output signal are used to estimate the at least one transmission parameter, and the filter coefficients are derived from the estimated transmission parameter.
