摘要：
A method and a circuitry for demodulating a digital frequency-modulated signal. After demodulating the digital frequency-modulated signal for generating the signal's amplitude and differential phase value &phgr;, the amplitude of the demodulated signal is compared with a constant at determined sampling times. The phase value of each sampling time is multiplied by a factor, the factor (c) being the product of the amplitude of the determined sampling time and the amplitude of a preceding sampling time, if the amplitude is less than the constant.
