Claim 3:
4. The fiber-optics sensor of claim 2 wherein the plurality of level-4 approximation coefficients are convoluted with the dB5 scaling function and downsampled to generate a plurality of level-5 approximation coefficients;
wherein the plurality of level-5 approximation coefficients are convoluted with the dB5 wavelet function and downsampled to generate a plurality of level-6 approximation coefficients;
wherein the plurality of level-6 approximation coefficients are upsampled and transformed with an inverse of the dB5 scaling function to generate the reconstructed dB5 level-6 approximation waveform that the respiration rate is extracted from.
