Biomedical Signal Analysis consists of measuring signals from biological sources, the origin
of which lies in various physiological processes. These signals based on their origin are classified
into different types, for instance, physiological signals originating because of electrical activity in
the heart are called electrocardiogram (ECG), while those originating because of electrical activity
in the brain are called electroencephalogram (EEG). Biological signals manifest themselves into
different forms such as electrical, acoustic, chemical, and many others. The analysis of these signals
is vital in diagnosing the pathological conditions and in deciding an appropriate care pathway.Many
times the underlying pathological processes result in different signatures and a good understanding
of the physiological system is necessary to understand the status of the system. For instance, a rise
in the temperature of the human body can convey infections in the body. Sometimes it can be a
consequence of a blood clot, which is good if it helps in stopping the bleeding but carries a risk of
heart attack or stroke.
