What is the effect of using both amplification and filtering in ECG measurements?.
- A.Increased risk of signal distortion
- B.Improved accuracy in heart signal detection
- C.Decreased time for ECG analysis
- D.Reduced need for electrode placement
Model answer
What a good answer should say
- Improved accuracy in heart signal detection
Explanation
Why this works
Using both amplification and filtering improves the accuracy in heart signal detection by ensuring that the signals are strong enough to be analyzed while minimizing noise interference. This combined effect allows for a more precise representation of the heart's electrical activity, leading to better diagnostic outcomes.
