First published in 1986: The presentation of the material in the book
follows the flow of events of the general signal processing system.
After the signal has been acquired, some manipulations are applied in
order to enhance the relevant information present in the signal. Simple,
Optimal, and adaptive filtering are examples of such manipulations. The
detection of wavelets is of importance in biomedical signals; they can
be detected from the enhanced signal by several methods. The signal very
often contains redundancies. When effective storing, transmission, or
automatic classification are required, these redundancies have to be
extracted.
