Abstract
The main objective of this paper is to analyze a zero crossing sampling digital phase-locked loop (PLL) as a building block for a phase synchronization system. To that purpose, the paper deals with modeling, analysis and implementation issues of the PLL. Derived are nonlinear and linear state-space models and a transfer function model. Operation of the PLL is also analyzed using frequency domain methods. An implementation of the PLL using a digital signal processor is described. On the basis of the derived models, two different system controllers are designed and the system transient response for the two cases is compared. The first controller is of a proportional-integral (PI) type and the second controller is minimum response time controller. It is shown how the input signal amplitude variations affect the system transient response. A solution for solving this problem is presented.

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
