A physiological-signal-analysis device for determining a blood pressure value of a patient and a method of operating the device. The device includes a cuff attachable to an extremity of the patient, a pneumatic system connected to the cuff that supplies a fluid to the cuff, a pressure transducer that measures the pressure signal having pressure oscillations, and a control unit connected to the pneumatic system and the pressure transducer. The control unit is operable to acquire a first oscillation having a first fiducial point, acquire a second oscillation having a second fiducial point, calculate a time interval representing a time from the first fiducial point to the second fiducial point, decide against selecting the second oscillation when the time interval is not a substantial integral multiple of a nominal oscillation period, and calculate a blood pressure value based on selected oscillations.
