Biomedical Signal Analysis, 2ed
The book presents digital signal processing and pattern recognition techniques for analysis of biomedical signals. It begins with an introduction on the nature of biomedical signals, such as the action potential, electrocardiogram, muscle signals, brain signals, heart sounds and speech. A detailed review of signals and systems is presented to set the stage for filtering of biomedical signals to remove noise and various artifacts. Several filtering techniques are presented with applications, from simple averaging to advanced and sophisticated optimal filtering methods. Techniques for detection and characterization of events and waves within a given signal are described.
