Abstract
A method is provided for operating an electrical device (14) which has an operating mode and a sleep mode, in which method an oscillator apparatus (20) provides a first analog signal (f(t)) with a first frequency and second analog signal (f′(t)) with a second frequency, wherein the second analog signal (f′(t)) is different from the first analog signal (f(t)), a comparator apparatus (28) compares the first analog signal (f(t)) and/or second analog signal (f′(t)) with at least one reference value (Uref) or a reference value range, and an interrupt signal for transferring from the sleep mode into the operating mode is produced if a certain comparison result is detected.
