摘要

A spectral interpretation using the frequency sensitivity of the Allan variance (Avar) and Theo-Hybrid (TheoH) is used to determine falpha noise, or "power-law noise." TheoH has narrower chi-square confidence than Avar; consequently, TheoH provides significantly better determination of falpha noise types at long term. Furthermore, TheoH has even narrower confidence than chi-square. Because the algorithms used to calculate these confidence intervals are computationally intensive, we have constructed an empirical formula that approximates confidence intervals as the percent error for TheoH
