Abstract
This work studies the prefilter bandwidth effects in four asynchronous sequential symbol synchronizers. We choose three different bandwidths, namely B1=∞, B2=2.tx and B3=1.tx, where tx is the bit rate. First, we developed various synchronous prototypes. After, we developed various asynchronous prototypes. The synchronizer has two variants, which are the reference standard operating by both transitions at bit rate and the new proposal operating by positive transitions at quarter bit rate. Each variant has two versions, namely the manual and the automatic. The objective is to study the prefilter with the four synchronizers and to evaluate their output jitter UIRMS (Unit Interval Root Mean Square) versus input SNR (Signal Noise Ratio).

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
