DIGITAL SIGNAL-PROCESSING .2. SPECTRAL-ANALYSIS

This is the second of two papers introducing the main topics in digita l signal processing. The subject of this paper is the estimation of th e spectra of signals and both classical estimation methods and modern model-based methods are discussed. These techniques are compared and r esults are presented which demonstrate the superior resolution which i s obtained with modern autoregressive spectral analysis methods. Examp les are given of the application of these techniques in the areas of s peech processing and biomedical signal analysis.
