ABSTRACT:
An apparatus for suppressing power frequency common mode interference in a bioelectrical signal measuring system includes a driving circuit configured to amplify and change the phase of a common mode interference signal to produce a first driving signal, wherein the common mode interference signal is extracted from a plurality of first electrodes attached to a patient; phase compensating and processing circuitry electrically connected to the driving circuit for receiving the first driving signal, the phase compensating and processing circuitry configured to produce a second driving signal by phase-compensating the first driving signal based on a characteristic value of power frequency interference in a bioelectrical signal acquired through the plurality of first electrodes; and a switch to receive the first driving signal and the second driving signal, the switch configured to selectively switch between providing the first driving signal and providing the second driving signal to a second electrode attached to the patient.
