Abstract
Presents an investigation of the design and real-time implementation of lossless discrete-integrator Jaumann digital filters. The salient feature of these digital filters is that they incorporate a minimal number of digital multipliers and have low sensitivity to multiplier coefficient and data wordlengths. Fast operational speed is achieved by using a Cauer-type structure which inherently is of the order of the transfer function to be realized. The investigation involves a fixed-point bit-serial implementation as well as a real-time floating-point digital signal processor (DSP) implementation using AT&T DSP32 and TI TMS320C30. Examples are given to illustrate the results. It is shown that it is possible to achieve a sample frequency of around 1 MHz in the case of a fixed-point implementation, and sample frequencies of about 180 kHz in the case of a floating-point DSP processor implementation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
