Title: An Electronic Stethescope Design
Author: Jackson, Greg; Lahartinger, Bryan; Smith, Adam
Abstract: In this paper, an electronic stethoscope for detection of heart defects in neonates is presented. The stethoscope filters the infants heart beat signal and then slows this signal down while maintaining the frequency information. The design consists of a signal processing algorithm running on an embedded processor while receiving a signal from a microphone. It costs $500 and is able to perform 60 examinations before it requires recharging.
