What is biosignal processing?

Biosignal processing is the analysis and interpretation of biological signals, such as those produced by the heart (ECG), brain (EEG), muscles (EMG), and other physiological systems. Professionals in this field use engineering and computational techniques to filter, analyze, and extract meaningful information from these signals for medical diagnostics, health monitoring, or research purposes. The field combines knowledge from biology, engineering, and computer science to help improve patient care and advance medical technology.
