摘要： A method for spectral analysis of a signal (s1(t)) in several frequency bands with different frequency resolution adapts the two spectra of the signal (s1(t)) from adjacent frequency bands relative to one another in the transitional range of the two frequency bands. The associated device contains a unit for discrete convolution (3), which implements a smoothing of the discrete power spectra (|S1(k)|2) of the discrete signal (s1(k)) from adjacent frequency bands in the transitional range of the two frequency bands.

摘要： A method and a system for the detection and/or removal of sinusoidal interference signals in/from a noise signal transforms a measured signal (x(t), x(μ·Δt)) composed of a limited number of sinusoidal interference signals (Ak·ej(ωkt+φk), Ak·ej(μ·ωkΔt+φk)) and a white noise signal (w(t), w(μ·Δt) into a subspace containing its white noise components and a subspace containing its interference signal components. Following this, the individual sinusoidal interference signals (Ak·ej(ωkt+φk), Ak·ej(μ·ωkΔt+φk)) are determined using an estimation method within the subspace containing the noise components. The entire frequency range is split into several frequency bands (v), in which the measured signal (x(t), x(μ·Δt)) consists of a limited number (p(v)) of sinusoidal interference signals (Ak·ej(ωkt+φk), Ak·ej(μ·ωkΔt+φk)) and a white noise signal (w(t), w(μ·Δt)).

摘要： A method and a device for determining a frequency mask disposed above or below a frequency spectrum of a detected signal determines every individual ordinate value of a first envelope curve disposed completely above or below the frequency spectrum as the maximum value or minimum value of a given number of respectively adjacent ordinate values of the frequency spectrum linked to a window function. Following this, each individual ordinate value of a second envelope curve disposed completely above or below the frequency spectrum and completely above or below the first envelope curve is determined as the maximum value or minimum value of a given number of respectively adjacent ordinate values of the frequency spectrum linked to a window function. Finally, a minimum number of ordinate values of the frequency mask from ordinate values of the first and/or second envelope curve disposed completely between the first and second envelope curve is determined, wherein in each case two successive ordinate values of the frequency mask with a maximum horizontal spacing distance within the first and second envelope curve can be reached in a linear manner relative to one another.

摘要： The invention relates to a method and a measuring device for determining a characteristic curve of a high frequency transmitter for transmitting a high frequency signal modulated with a modulation signal. A high frequency signal transmitted by the high frequency transmitter is received by a receiving device (16) and samples of a complex value, real baseband signal (MEAS) are generated therefrom. By demodulation of the samples of the real baseband signal (MEAS), a modulation symbol sequence (SYM) is obtained, from which an ideal baseband signal (REF) is simulated as reference signal. The real baseband signal (MEAS) is corrected, a corrected, real baseband signal (MEAS′) is generated and the deviations of the samples of the corrected, real baseband signal (MEAS′) from the samples of the ideal baseband signal (REF) are evaluated.

摘要： A circuit for the continuous and uninterrupted read-in of a large data volume of an electronic measuring device into a memory, having at least two dynamic storage elements (2a, 2b) each of which can accept only one data volume uninterrupted during an active phase (which data volume is limited relative to the total data volume to be read in) and must be prepared again for a new read-in during an inactive phase. These storage elements are so controlled via a control circuit (3) that during the inactive phase of a first storage element (e.g. 2a), the data are read into a second storage element (e.g. 2b) which is prepared for the active phase, and when this second storage element must be prepared again, there is an automatic and uninterrupted changeover to another storage element (e.g. 2a) which is already prepared for the active phase, until the total data volume is read in.

摘要： A device for measuring the phase-noise spectrum of a pulsed sinusoidal signal generates a pulsed sinusoidal signal, converts the analog pulsed sinusoidal signal into a corresponding digital, pulsed sinusoidal signal and mixes the digital, pulsed sinusoidal signal into the baseband by means of quadrature mixing. Following this, the phase of the pulsed sinusoidal signal in the baseband is determined by means of Fourier transform of the phase of the pulsed sinusoidal signal, the phase spectrum of the pulsed sinusoidal signal is determined, and the phase-noise spectrum of the pulsed sinusoidal signal is determined by removing the spectral lines associated with the sinusoidal signal from the phase spectrum. According to the invention, the pulse pauses are removed from the pulsed sinusoidal signal in the baseband.
