1. A method for processing pulses from a PPG signal, comprising:

  • receiving a PPG signal;

    performing a continuous wavelet transform of the PPG signal to produce a wavelet transformed signal;

    generating a scalogram from the transformed signal;

    identifying regions in the scalogram corresponding to desired components of the PPG signal;

    identifying pulse locations in the PPG signal based on the identified regions; and

    replacing at least one pulse in at least one of the identified pulse locations in the PPG signal with a pulse selected from the group comprising a triangular pulse, a square pulse, and a sinusoid pulse.
