Describe the term "biomedical signal."

The term "biomedical signal" refers to a quantitative representation of biological phenomena. This encompasses any measurable data that reflects the physiological processes of biological systems, which can be captured through various monitoring devices or sensors. Biomedical signals can include parameters like heart rate, blood pressure, and brain waves, each of which provides valuable insight into the functioning of the body.

Understanding biomedical signals is crucial in the field of biomedical engineering, as they are used for diagnosis, monitoring, and treatment of patients. The ability to quantify these biological interactions allows healthcare professionals to make informed decisions based on reliable, objective data. Thus, when we refer to biomedical signals, we are emphasizing the importance of quantifying biological activities to enhance clinical care and research.
