Design of electronic instrumentation and measurement systems
Winter 2024 - Dartmouth College
In the Biomedical Circuits & Systems course, I engaged deeply with the fundamental principles of electronic instrumentation and measurement systems design. Throughout the course, I gained experience in:
-Understanding the operation and application of various transducers in biomedical contexts.
-Designing sensor interface circuits to ensure accurate data acquisition and processing.
-Employing different analog-to-digital converters for the conversion of analog signals into digital data.
-Implementing signal processing algorithms to extract relevant information from biomedical signals.
-Developing proficiency in event-driven microcontroller programming for real-time control and data processing.
Collaborating closely with my lab partner, we successfully constructed several biomedical devices, including an ECG-based heart rate monitor, an electronic stethoscope, an automatic blood pressure monitor, and a blood oxygenation monitor. Screen grabs showcasing the development and testing stages of these circuits are available for review.
