Basic knowledge of electronics and signal processing

• Introduction
• Characteristics of surface, needle and micro electrodes
• Equivalent circuit of skin- electrolyte-electrodes interfaces
• Subdivision criteria of biomedical instrumentation and block diagram of equipments for biosignal acquisition
• Specific characteristics of: bioelectrical signals (action potential, ENG, EMG, ERG, EOG, EEG, VEP, ECG, foetal ECG, V-ECG), acoustic signals (phonocardiograph, speech, Korotkoff sounds), mechanical signals (blood pressure, apex-cardiograph), biomagnetical signals (MEG)
 Measurements of: impedance (pletismograph, pneumograph, oculograph, elettroglottograph, acoustic impedance-meter and tympanometer), flow (pneumotachograph, electromagnetic flowmeter), volume (inspirometer, dilution, photopletismograph)
• Main measurement on: cardiocirculatory system, breathing system, central nervous system, peripheral nervous system, autonomic nervous system
• Ocular movements and acquisition systems (search coil, EOG, IR, VOG)
• (Chemical) Laboratory: spectrophotometer, fluorometer, blood CO2, O2 and pH measurements, chromatography, electrophoresis, haematology
