Numerical Calculation of Microthermal Temporal Spectra

Abstract

This report presents and discusses several accepted techniques employed in the digital estimation of power spectra. These methods were applied to the calculation of power spectra of microthermal fluctuations. Discussed herein are such topics as preliminary data management, data windows, pre- whitening and post-darkening, confidence intervals, digital filtering, and the use of the fast Fourier transform algorithm (FFT).
