This collection of technical reports deals with estimation of spectra of stationary processes, both by the now-standard direct approach and by the more recent autoregressive approach. The topics range over numerical procedures involving Fast Fourier Transforms, cross-spectral estimation, minimum bias windows, vernier FFTs, coherence, univariate and multivariate maximum entropy spectral estimation, and probability distributions special estimates. These results, which were new when published, are still of great relevance to anyone doing spectral analysis who is interested in obtaining good resolution and stability from limited record lengths.
