Abstract: The present invention provides a method and an apparatus for measuring a light absorption spectra which can remove a noise included in a measurement signal, and achieve a high sensitivity of a laser spectral in a good S/N ratio. According to the present invention, there is provided a method for measuring a light absorption spectra comprising the steps of: (i) conducting a Fourier transform of an absorption spectra measured by using a laser beam source; (ii) disassembling in a Fourier space the Fourier transformed signal into a signal resulted from a periodic vibration component and a signal resulted from a molecular absorption spectra; (iii) removing the Fourier component resulted from said periodic vibration component in a Fourier space; and (iv) conducting an inverse Fourier transform on the signal from which said periodic vibration component is removed, whereby reproducing an absorption spectra in a real space.

Abstract: An automatic network analyzer that measures continuous wave radio microwave driven transfer characteristics of nonlinear devices and simultaneously calculates and displays corresponding noise driven transfer characteristics and noise power ratio data. This automatic network analyzer employs software or firmware that uses closed-form equations to exactly calculate noise parameters. This is done in real-time as CW measurements are taken.

Abstract: A processor-based device supports performance optimization with use of an adaptive digital element. The adaptive digital element generates probability data corresponding to a probability of a performance parameter of the processor-based device. The probability data is repeatedly compared to input data corresponding to the performance parameter and is adapted to match the input data. After a predetermined number of samples, a probability value corresponding to the probability data and stored in a counter of the adaptive digital element converges to a good estimated probability of the performance parameter. The probability value is then detected and processed, and the processor-based device is adapted in accordance with the probability value. A processor of the processor-based device also can adapt system operation when the probability value reaches a predetermined trigger value.
