1. A subject monitoring system for conditioning a physiological intensity signal, comprising:

  • a sensor configured to generate a physiological signal, wherein the sensor detects light attenuated by a subject; and

    processing equipment coupled to the sensor, wherein the processing equipment is configured to;

    determine a value indicative of a physiological rate based on the physiological signal;

    determine a metric based on the physiological signal;

    select one or more bandpass filter settings of a bandpass filter based on the physiological rate and based on the metric; and

    apply the bandpass filter with the selected one or more bandpass filter settings to the physiological signal to generate a filtered signal.
