Abstract
A biological signal measuring apparatus is provided. The biological signal measuring apparatus includes a receiving unit configured to receive a biological signal from each of unit measurers arrayed on a subject's skin, and configured to receive a noise signal that is a common component of electrical characteristics, and a noise filtering unit configured to filter noise from a first biological signal between first electrodes of a first unit measurer among the unit measurers, by using a second noise signal between second electrodes of a second unit measurer among the unit measurers. The biological signal corresponds to a difference between the electrical characteristics of electrodes of each of the unit measurers.
