Kurzbeschreibung
Signal analysis attempts to arrive at a structural description of a signal so that later high-level algorithms can interpret its content. Responding to a need for a complete introduction to this growing field, this thorough overview discusses the major aspects of signal analysis, from analog and discrete signals, linear systems, and analog and discrete Fourier transforms to sampling theory and random signals.
Offers a well-rounded, mathematical approach to problems in signal interpretation using the latest time, frequency, and mixed-domain methods
* Equally useful as a reference, an up-to-date review, a learning tool, and a resource for signal analysis techniques
* Provides a gradual introduction to the mathematics so that the less mathematically adept reader will not be overwhelmed with instant hard analysis
* Covers Hilbert spaces, complex analysis, distributions, random signals, analog Fourier transforms, and more
