• Resumen

  • A standardized approach to acquire, calculate, and display noise spectra is proposed. The method is based on normalizing the noise amplitude spectrum to the average dc level of the input signal. This normalization procedure should allow noise spectra, obtained in different laboratories or from different sources, to be compared both quantitatively and qualitatively. A review of the proper techniques to acquire and compute noise spectra is also given.
