    Abstract: A signal processing method and apparatus for measuring heartbeat and oxygen saturation. The signal processing apparatus may acquire a first sampled signal by sampling a detection signal output from an optical detector in an interval in which a light source is activated, may acquire a second sampled signal by sampling a detection signal output from the optical detector in an interval in which the light source is inactivated, and may output a combined signal in which the first sampled signal and the second sampled signal are combined. An amplitude of the first sampled signal may decrease by combining the first sampled signal with the second sampled signal.
