Abstract
A method for estimating a property of a signal () sensed in an electrical system, comprises the steps of sensing the signal () and estimating a fundamental period of a fundamental of the signal () by comparing the sensed signal () with at least one threshold () to detect threshold crossings and estimating the fundamental period from the threshold crossings. The signal property is then estimated from the fundamental period and/or from the sensed signal () during an interval of a length of the fundamental period. An electronic device according to the invention comprises a micro controller and/or an analogue circuitry which performs the method for estimating a property of a signal. Preferably, the micro controller and/or analogue circuitry controls other parts of the electronic device depending on the results obtained by the method for estimating a property of a signal.
