发明名称 Method and apparatus of signal processing for use in spectrometry using an improved apodization function
摘要 A method and apparatus is disclosed for signal spectrometry using an improved apodization function. Such method and apparatus involve (i) obtaining sample and reference time domain waveforms; (ii) applying sample and reference apodization waveforms to the sample and reference time domain waveforms, such that substantially same weight is applied to corresponding substantially coextensive regions of the sample and reference time domain waveforms, (iii) transforming the sample and reference apodized waveforms from the time domain into the frequency domain; and (iv) generating referenced spectral analysis waveform for signal analysis from a ratio of the transformed sample and reference frequency spectra, the spectral analysis waveform substantially excluding frequencies associated with the corresponding substantially coextensive regions of the apodized sample and reference time domain waveforms.
