Hi-Accuracy Method for Spectrum Shift Determination

Hi-Accuracy Method for Spectrum Shift Determination

A new hi-accuracy method for slight-shift determination of low-resolution spectra is proposed. The method allows determining a spectrum shift with an accuracy exceeding the spectrum analyzer resolution to more than three orders of magnitude due to the mathematical post-processing. The method is base...
