The course describes the fundamental characteristics of the biomedical instrumentation focusing on all aspects related to the electronics of a system for the acquisition and processing of biomedical signals. A substantial part of the course will be dedicated to the design and assembly of the analog front-end of a device for heart rate monitoring.
