Several studies [1,2] have shown the potential of EIT to estimate cardiovascular parameters. To achieve this goal, EIT devices have to deal with small impedance variations. As a consequence, the high value of the direct component (DC) of the bio-impedance signal becomes an issue in terms of analog to digital converter resolution. With this research, we aim at demonstrating that the DC of the signal can be discarded before digitalization.
