Challenge Problems
Push your limits with challenges.
Question 1
Analyze a hypothetical situation where a therapist uses a bipolar A/D converter to track emotional responses based on changes in heart rate, which may drop below and rise above an average baseline value during therapy sessions. Discuss the implications of using unipolar conversion in such a context.
💡 Hint: Consider the range of heart rate variations.
Question 2
Transfer your understanding of bipolar mode into a practical device such as an ECG machine. Discuss the extremes of input voltages and how bipolar conversion impacts diagnostics.
💡 Hint: Think about how heart signals behave over time.
