Abstract
A broadband digital beamforming algorithm is proposed for directional filtering of temporally-broadband bandpass space-time (ST) plane-waves (PWs) at radio frequencies (RFs).The enhancement of desired waves, as well as rejection of undesired interfering PWs, is simulated.A massively-parallel synchronous and asynchronous array architecture is proposed for the real-time implementation of 2 nd -order two-dimensional (2D) infinite impulse response (IIR) spatially-bandpass (SBP) beam filters having potential applications in broadband beamforming of temporally downconverted RF signals.The higher speed of operation and potentially reduced power consumption of the asynchronous architecture in comparison to the conventional synchronous hardware have emerging applications in radio-astronomy, radar, navigation, space science, cognitive radio and wireless communications.Further, the bit error rate (BER) performance improvement along with the reduced computational complexity of these digital filters over digital phased array feed (PAF) beamformer is provided.A nominal BER versus signal-to-interference ratio (SIR) gain of 2 -3 dB at approximately half the number of parallel multipliers compared to digital PAF, is observed.A novel discrete-space continuous-time (DSCT) analog circuit implementation of the 2D IIR SBP beam filter using ideal operational amplifiers is also proposed.iii

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
