Abstract:

A guide to digital spectral analysis is presented. The emphasis is on a practical engineering understanding of the techniques, based on experience gained in their application to the analysis of flight measurements of aircraft vibration in buffet. Consequently, particular attention is directed to the practical difficulties encountered when the duration of the available data is severely limited, and to the use of the coherence function as a tool in the interpretation of complicated responses. However, the presentation of the fundamental principles, and especially the inherent limitations of the techniques are relevant to any sphere of application. Author
