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.

摘要： In a cascaded sigma-delta modulator, in particular for converting time-discrete samples into corresponding analogue signals in digital radio communication receiving devices, the error signal of a sigma-delta modulator of the cascade being fed to a next sigma-delta modulator of this cascade, the output signal yi−1(k) of the preceding i-1 sigma-delta modulator is also fed to the decision circuit of the ith sigma-delta modulator of the cascade.

摘要： An apparatus produces a reduction signal for a signal having a plurality of subcarriers. The apparatus has a limiter which is designed to produce a limited signal from the signal having a plurality of subcarriers; -a coefficient ascertainment unit which is designed to determine coefficients for unused subcarriers of the signal having a plurality of subcarriers from the limited signal; and -a signal generator which is designed to generate the reduction signal from the coefficients. The reduction signal is able to be combined with the signal in order to form a reduced signal. The coefficient ascertainment unit is designed to project the limited signals onto a K-th base formula.

摘要： A method for influencing the channel separation of an audio signal to be reproduced, obtained from a received radio signal, in a radio receiver, as well as a radio receiver for carrying out the method includes an auxiliary field strength signal derived from the received field strength of the received radio signal, and an auxiliary interference signal derived from signals indicating reception interference events, being combined with one another and with an auxiliary channel separation signal that is derived from a signal indicating the frequency of interference events, to yield a factor D which influences the stereo channel separation.
