Abstract
Two new analytical synthesis methods are proposed for synthesising an n th odd‐order elliptic high‐pass (HP) filter using operational trans‐resistance amplifiers (OTRAs). The analytical synthesis scheme is based on the assumption of infinite trans‐resistance R m for the OTRA. The H‐spice simulations of the realised elliptic third‐order HP filters show that the realisation using less number of OTRAs has a performance better than that which uses more number of OTRAs, as is to be expected in view of the assumption that R m is infinite, when in fact it is finite in practice. However, it is shown that by slightly adjusting a single resistor, the amplitude–frequency response can be made close to the theoretical response.

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
