In this paper we present a new design of a modified stethoscope. The main objective is to enable the early detection of heart defects in newborn infants. The design uses signal processing to enable the improvement of detection. The design was simulated and the results show that the device would make detection of defects much more precise and efficient.


Created in fulfillment of the course requirements for ENGG*3100 Engineering and Design III. This course combines the knowledge gained in the advanced engineering and basic science courses with the design skills taught in ENGG*1100 and ENGG*2100 in solving open-ended problems. These problems are related to the student's major. Additional design tools are presented, including model simulation, sensitivity analysis, linear programming, knowledge-based systems and computer programming. Complementing these tools are discussions on writing and public speaking techniques, codes, safety issues, environmental assessment and professional management. These topics are taught with the consideration of available resources and cost.
