Abstract
Abstract — Any digitization system must be preceded by an anti-aliasing filter. For wideband high frequency applications, parallel multi-rate conversion systems such as time-interleaved or hybrid filter bank analog-to-digital converters (resp. TI-ADC or HFB) are attractive solutions. This paper compares the robustness of both techniques with respect to non-idealities of the anti-aliasing filter (AAF). Theoretical results show that the signal-to-noise ratio (SNR) degradation due to out-of-band signals is lesser for HFBs than for TI-ADCs, provided that the analysis filters of the HFB are selective enough. Simulation results show that this is the case even for low-order analysis filters in the case of a four-channel HFB. I.

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
