Abstract
Electrocardiography (ECG) signal is currently recorded using minimum three electrodes, two electrodes for differential measurements and the third one to increase the Common Mode Rejection Ratio (CMRR). This paper presents a method to increase the CMRR of the analog front-end of ECG circuits. It is shown that the CMRR of ECG systems can be improved significantly without the need to the third electrode using a feed-forward method. It is also shown that the implemented ECG circuit can outperform the conventional right-leg driven systems when the signal paths are matched. The presented scheme can also be used with the right-leg driven circuit to further improve the CMRR.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
