Abstract :
The paper presents hardware and software interfacing to the line-in audio channel standard connection of fixed and mobile computing terminals, for the conditioning and acquisition of out-band signals - the case studies cover mostly lower frequencies [1], with focus on EKG, but higher spectra are also addressed (via sub-coherent under-sampling).
