ABSTRACT:
A preferred oximeter detects the transillumination by red and infrared light of a portion of an in vivo subject and produces analog signals representative thereof on two channels. Sigma-delta modulators sample the analog signals on each channel. A digital filter processor digitally filters the sample signals from both modulators to produce respective digital signals with multi-bit resolution.
