Abstract:
1. An electronic device, intended to carry out the measurement and the detection of variations of at least one input signal, comprising: a first component providing an output signal whose oscillation frequency is representative of the input signal, a reference oscillator, a phase comparison component carrying out a comparison between the oscillations of the first component and of the reference oscillator, in particular for the purpose of a slaving by a loop of the reference oscillator to the first component, or of the first component to the reference oscillator, or of a mutual slaving, and elastic means of coupling between the first component and the reference oscillator, wherein the electronic device comprises synchronization means designed to block or permit alternatively influence of the oscillations of the first component on the phase comparison component and on the coupling means, and means for determining a derived signal from an evolution of the output signal from the phase comparison component.
