Abstract (en)

[origin: WO2015181031A1] Method for processing a signal modulated with a variable carrier frequency, in particular of a sensor arrangement, comprising the steps: - calculating a coefficient (c(n)) to demodulate the signal; - demodulating the signal by calculating discrete intermediate values (s, s1, s2) by means of the coefficient for a predefined maximum number of steps (n_max), and calculating the signal on the basis of the intermediate values and a coefficient (c(n)), wherein a Goertzel filter is used in order to calculate an amplitude component.
