Abstract
A frequency modulation method is provided in which the frequency of a carrier signal is modulated on the basis of the frequency of a modulation signal, and in which the modulation signal is integrated. The carrier signal is integrated, and a differential signal is formed from the integrated modulation signal and the integrated carrier signal. The differential signal is phase-modulated in order to obtain the frequency-modulated carrier signal as the output signal.
