AN ULTRA-LOW POWER SUBBAND-BASED ELECTRONIC STETHOSCOPE
Auscultation continues to be a routine part of
cardiovascular and pulmonary examinations. Recently,
there have been a number of advances in auscultation
technology, including the introduction of a number of
electronic stethoscopes [1,2,3]. Many of these stethoscopes
rely on the use of a personal computer to filter, record and
replay the signal. As such, these systems are large and have
limited portability. Little emphasis has been placed on
generating high quality audio in a small, portable unit.
Clearly, an electronic stethoscope system with the features
of these larger systems that is portable and low power
would be advantageous.
