Abstract: Sample values of a digital signal of a first sample rate are supplied to a digital filter for conversion into a digital signal of a second sample rate. The coefficients of the digital filter are calculated by a processor from the ratio of the sample rates or are obtained by a read-only memory containing sets of coefficients for respective sample rate ratios for which the apparatus is usable. Filtered sample values are read out of the digital filter at the desired second sample rate. A buffer memory is used at the input of the digital filter and a regulator is provided to prevent fluctuations in the filling of the buffer memory from emptying or exceeding the capacity of the buffer memory.

Abstract: 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.

Abstract: A circuit arrangement for deriving the signal indicating noise in a received stereo multiplex signal, wherein the stereo multiplex signal is present as a digital signal with a first sampling rate that is substantially higher than twice the upper limit of the useful frequency range of the stereo multiplex signal, and the received stereo multiplex signal is passed through a low-pass filter. The low-pass filtered signal and the received stereo multiplex signal are subjected to decimation to a second sampling rate, which is higher than twice the upper limit of the useful frequency range of the stereo multiplex signal. The two stereo multiplex signals with the second sampling rate are subtracted from one another.

Abstract: In a radio receiver with digital signal processing, a stereo multiplex signal received and the useful signals derived therefrom are processed in digital form at a first sampling rate. The subsidiary signals derived from the stereo multiplex signal are at least partly processed at a second sampling rate that is smaller than the first sampling rate. The sampling rate of the processed subsidiary signals are reduced to the first sampling rate with the processed subsidiary signals, acting as control signals with the first sampling rate, affecting the stereo multiplex signal and the useful signals.

Abstract: In a circuit for a demodulator of a radio data signal in a radio receiver, the multiplex signal in digital form is mixed into the baseband, in two phase positions shifted 90.degree. with respect to each other, after band-pass filtering, together with a reference carrier generated at a sampling clock rate produced in the radio receiver, thus producing a first and a second mix signal. A first and a second auxiliary signal with, respectively, a sine waveform and a cosine waveform are produced. The first mix signal is multiplied by the first auxiliary signal, and the second mix signal by the second auxiliary signal. The results of these multiplications are added together, producing a first output signal. The first mix signal is multiplied by the second auxiliary signal, and the second mix signal by the first auxiliary signal, and the results subtracted from each other, thus producing a second output signal. The phase position of the auxiliary signals is controlled in such a manner that the first output signal corresponds to the radio data signal (RDS) shifted down into the baseband.
