1. An apparatus for integrally processing a plurality of biologic signals, the apparatus comprising: a first signal processing module which generates a signal for operating a sensing module including a plurality of sensor groups which measures the plurality of biologic signals, and which processes a biologic signal provided from the plurality of sensor groups based on a control signal; and a second signal processing module which authenticates a sensor group from among the plurality of sensor groups, generates the control signal according to a result of the authentication while automatically setting a processing condition, processes the biologic signal provided from the first signal processing module according to the processing condition and outputs a result of processing the biologic signal.
