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.
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.
The Signal Processing Labs use the BIOPAC SS39L Signal Processing Breadboard with Interface Cables and Electrode Interface. The human body can be studied by viewing the potential difference (Voltage) between strategically placed surface electrodes. In order to view and record the potential difference between surface electrodes, electronic circuits are used. Electrode leads, which are essentially wires, 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.
