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.
