1. A method of determining of a physiological parameter of a monitored patient attached to a noninvasive optical sensor, the method including electronically processing signals indicative of attenuation by body tissue of the patient, the method comprising:

  • receiving one or more signals indicative of light attenuated by body tissue of pulsing blood in said monitored patient, said one or more signals usable to determine measurements for one or more physiological parameters of said monitored patient;

    electronically determining an initial frequency estimate related to said one or more physiological parameters;

    electronically combining at least one sinusoidal waveform with said one or more of said signals to produce a predetermined signal response; and

    electronically processing the combined signal to determine an output measurement of one or more of said one or more physiological parameters.
