UNIT I BIO POTENTIAL GENERATION AND ELECTRODES TYPES
Origin of bio potential and its propagation. Types of electrodes - surface, needle and micro electrodes
and their equivalent circuits. Recording problems - measurement with two electrodes
UNIT II BIOSIGNAL CHARACTERISTICS AND ELECTRODECONFIGURATIONS
Bio signals characteristics – frequency and amplitude ranges. ECG – Einthoven’s triangle, standard
12 lead system. EEG – 10-20 electrode system, unipolar, bipolar and average mode. EMG– unipolar
and bipolar mode.
UNIT III SIGNAL CONDITIONING CIRCUITS
