Spectral Analysis and Spectral Synthesis
2012Spectral analysis and spectral synthesis deal with the description of translation invariant function spaces over locally compact Abelian groups. One considers the space Open image in new window of all complex valued continuous functions on a locally compact Abelian group G, which is a locally convex topological linear space with respect to the point ...

Spectral analysis of hypernasality
2010The aim of this study was to further investigate one-third-octave analysis by (a) extending the application of the analysis to three vowels, /inverted a sign/, /inverted c sign/ and /u/, in addition to /i/ which has been investigated previously, and by (b) comparing the spectra of each vowel produced in oral and nasal consonant contexts for each ...

Abstract In Section 2.7 we introduced the periodogram as a way of representing the variability in a time series in terms of harmonic components at various frequencies. We defined the periodogram ordinate at a particular frequency w to be proportional to the squared amplitude of the corresponding cosine wave, α cos(ω t)+ β sin( ω t ...
