摘要： Die Erfindung betrifft ein Verfahren zur Bestimmung der Frequenz eines Signals, wobei ein analoges Signal durch eine digitale Filterung, vorzugsweise eine FFT, in die komplexe Frequenzebene umgesetzt wird, so daß in dieser Ergebnisvektoren mit einem Amplituden- und einem Phasenanteil entstehen. Dabei entsteht innerhalb eines vorgebbaren Meßzeitraumes eine lückenlose Folge von Transformations-Intervallen (FFT-Intervallen). Aus vorgebbaren Transformations-Intervallen (FFT-Intervallen) werden nun paarweise Ergebnisvektoren, die zu derselben vorgebbaren Frequenz gehören, ausgewählt. Es werden zugehörige Phasendifferenzen gebildet und damit eine gewichtete Phasendifferenz ermittelt. Mit dieser wird die aus dem Amplitudenspektrum ermittelte Frequenz des Signals korrigiert. Mit dem Verfahren ist eine genaue Frequenzmessung möglich, insbesondere bei gepulsten HF-Signalen.

摘要： A measuring method for determining the amplitude and the phase of the fundamental tone/frequency of an alternating voltage in an ac network wherein the determination is performed in a numerical relay (12) which is based on a constant sampling frequency and which comprises a Fourier filter (7) for determining the amplitude and the phase of the alternating voltage, which measuring method is characterized in that the Fourier filter is an adaptative Fournier filter which is adapted in such a way with respect to the number of sample points that the deviation between the filter frequency of the adaptive filter, adapted to the nominal fundamental tone/frequency of the ac network, and a fundamental tone/frequency determined with a calculating unit (10) is minimized.

摘要： A signal to be analysed is fed from input terminal 1 to analog-digital converter 6. The resulting digital signal is fed in parallel to digital low- (or high-) pass filters 16 to 22. The outputs of filters 16 to 22 are fed to square circuits 23-1 to 23-7. Subtraction circuits 24-1 to 24-6 receive the outputs of respective pairs of square circuits (e.g. subtraction circuit 24-1 receives the outputs of square circuits 23-1, 23-2, and subtraction circuit 24-2 receives the outputs of square circuits 23-2, 23-3). The subtraction circuits 24-1 to 24-6 derive differences between the outputs of the pairs of square circuits to which they are connected. The differences are fed to accumulators 25-1 to 25-6 which accumulate received differences over a period of time then output accumulated values. The output accuulated values give indications of power levels in different frequency bands of the signal to be analyzed over the period of time concerned.

摘要： [Problem] To make it possible to detect the peak frequency of a signal wave at a desired frequency resolution and in a desired time window length while avoiding a conflicting relationship between the frequency resolution (f 0 ) and the time window length (T 0 ). [Solution] A peak frequency detection device that detects a peak frequency at which the maximum power spectrum is achieved in a predetermined frequency band (f cl to f ch ), said peak frequency detection device being provided with: an n multiplication unit that multiplies each element of a digital data string by n (n is an integer of 2 or more); an FFT unit that derives, as a virtual peak frequency, a frequency that corresponds to the maximum value of a power spectrum that is obtained by performing a fast Fourier transform of a digital data string of N (N is an integer of a power of 2 and is determined in accordance with a sampling frequency (f s ), a sampling resolution (f tg ), and a time window length (T tg )) sample frequencies (f s ) that are multiplied by n; and a 1/n multiplication unit that outputs the value of the virtual peak frequency multiplied by 1/n as the peak frequency of the digital data string. The peak frequency detection device satisfies n ‰¥ 1/(f tg ×T tg ), f s /(n×f tg ) ‰¤ N ‰¤ f s ×T tg , and f s > 2×n×f ch .
