Signal processing / Personal project
Biomedical ECG Signal Processing
Filtering noisy ECG signals and analyzing QRS peaks.
The problem
Reduce powerline, baseline-wander and sensor noise.
The approach
50 Hz notch and 0.5–40 Hz Butterworth filtering, with beat-by-beat QRS and SNR analysis.
Results and scope
- Validated signal restoration with SNR gain and peak detection.
