Abstract
Exemplary embodiments relates to a demodulator for frequency-shift keyed signals by using the Goertzel algorithm according to the general recursive calculating rule, where with the sampling frequency fand the specified frequency f. To reduce the mathematical complexity in feed-power-limited devices, it is proposed that the sampling frequency fis an integral multiple of the frequency fof a specified discrete spectral component.
