Study more about the Vital Organ called Heart, by building an Electronic Stethoscope. See the Block Diagram (SBD) – Digital Stethoscope – TI.com. The sounds are very faint and a low frequency. It is a Bionic Challenge to acquire and amplify these small signals. Learn more about these concepts here …
The SS30L Electronic Stethoscope will allow you to record and listen to heart sounds and Korotkoff sounds.
Here is a another Semiconductor Application from Maxim-IC Digital Stethoscope.
