BSL PRO Signal Processing Labs are a series of lessons that explain how to create and test the types of electronic circuits used in Biomedical Engineering (BME). The Signal Processing Labs use the BIOPAC SS39L Signal Processing Breadboard with Interface Cables and Electrode Interface.
Students learn that the human body can be studied by viewing the potential difference (Voltage) between strategically placed surface electrodes, and use electronic circuits to view and record the potential difference between surface electrodes. Electrode leads connect the electrodes to the circuit. Most signals from physiological activity have small amplitudes and must be amplified and processed before they can be viewed in a meaningful way.
Concepts introduced include the basics of amplifiers (with special emphasis on the biopotentials), Gain, Common-mode rejection (CMR), Electrode polarization, Frequency response, Input impedance, Signal noise and drift, Filters, and ECG circuit requirements.

There is overwhelming evidence that combining multiple physiological measures provides greater power to discriminate mental workload as well as other cognitive states. Researchers frequently acquire disparate data streams for studies in cognition, human factors, ergonomics, user experience, and more.
