The invention relates to a method for automatic identification of the spectral components of a signal, comprising the following stages: application of a predetermined plurality N of distinct transformations to the signal in order to provide N signal spectra; automatic detection in each spectrum of ...
What are the components? Single-sideband phase noise There are many ways to define spectral purity. The most common and meaningful method of specifying short-term stability is a plot of the signal generator’s single-sideband (SSB) phase noise in a 1 Hz bandwidth versus the offset from the ...
The goal of this paper is to construct an approximate maximum-likelihood estimator to accurately estimate the period and spectral contents of a noisy periodic signal that has many frequency components. This is accomplished without user interaction. The signal data record has a total number of periods...
The spectral analysis of a signal displayed by time-domain provides a “fingerprint” of the signal and establishes a one-to-one relationship between time and frequency-domains. The spectrum, which is the method of representing spectral analysis, is another way of seeing the signal and of great...

The Hierarchical segments, calculated using a set of connected components obtained by performing a set of morphological operations on each individual band are bundled together based on a measure calculated using spectral homogeneity and neighbourhood connectivity [127] [30]. The Expectation-Maximisation ...
The neutral He absorptions apparently do not follow the orbital motion of any of the binary components, thus they most probably arise in a third star in the system. 展开 关键词: binaries: spectroscopic stars: individual: HD 150136 DOI: 10.1111/j.1365-2966.2004.08513.x 年份: 2005 ...

Spectral parameters of the R-R variability signal are obtained as follows: total power, power of low-frequency (LF) and high-frequency (HF) components, power of the signal which is (or is not) coherent with respiration, in absolute or in percentage values. The experimental protocol considers...
