Claim Text:
1. A biological signal measuring apparatus comprising: a receiving unit configured to receive a first biological signal and a first noise signal from a first unit measurer arrayed on a subject's skin through a noise detecting unit and to receive a second biological signal and a second noise signal from a second unit measurer arrayed on the subject's skin through the noise detecting unit, the first biological signal corresponding to a difference between electrical characteristics of first electrodes of the first unit measurer, the first noise signal being generated based on a common component detected from electrical characteristics of the first electrodes of the first unit measurer, the second biological signal corresponding to a difference between electrical characteristics of second electrodes of the second unit measurer, and the second noise signal being generated based on a common component detected from electrical characteristics of the second electrodes of the second unit measurer, wherein the noise detecting unit is configured to amplify and invert the first noise signal and amplify the second noise signal; and a noise filtering unit configured to filter noise from the first biological signal between the first electrodes of the first unit measurer among the two unit measurers, using the second noise signal between second electrodes of the second unit measurer among the two unit measurers.
