Sample Experiment: RC Low-Pass Filter Frequency Response
Reference page. This page was prepared for the NSF PCL FAIR-data due diligence (July 2026) as a working sample of how every Adom experiment is published. The experiment is a computed characterization: a closed-form model evaluated by the included code, not a bench measurement: and is fully reproducible bit-for-bit from the files on this page. Real bench experiments follow this exact same structure, with instrument captures (oscilloscope/spectrum-analyzer screenshots and CSV/JSON exports) in place of the model.
Objective
Characterize the frequency response (magnitude and phase) of a first-order RC low-pass filter (R = 1 kΩ, C = 100 nF) from 10 Hz to 1 MHz, and publish the result the standard Adom way: write-up + JSONL dataset + sidecar metadata + provenance + the AI skill that reproduces it.
Method
The transfer function H(f) = 1 / (1 + j·2πf·RC) is evaluated at 20 points per decade
(101 points total). Expected cutoff: fc = 1/(2πRC) ≈ 1591.5 Hz. The whole run is
deterministic: python3 analysis/run_experiment.py regenerates the dataset, its
sidecar, and the plot exactly.
Results
| Check | Expected | Measured (dataset) |
|---|---|---|
| Gain at fc | −3.01 dB | −2.99 dB (at 1584.9 Hz grid point) |
| Phase at fc | −45° | −44.88° |
| Rolloff past fc | −20 dB/decade | −56.0 dB at 1 MHz (2.8 decades) ✓ |
How the data is organized (the part NSF asked about)
| FAIR concern | Where it lives on this page |
|---|---|
| Data | data/rc_lowpass_response.jsonl: one JSON row per point: frequency_hz, gain_linear, gain_db, phase_deg |
| Metadata | data/rc_lowpass_response.sidecar.json: the sidecar JSON is the dataset's metadata, a small file that rides alongside the data with its schema (fields + units), parameters, generator, row count, sha256, and license |
| Provenance | provenance.json: who ran it (human-prompted, AI-executed), the input model and code, design-reference part numbers, output hashes, and the full chain from request to publication |
| Reproducibility | skills/reproduce-rc-characterization/SKILL.md: the AI skill; one command regenerates everything |
| Persistent identifier | this page's URL: wiki.adom.inc/adom/sample-experiment-rc-lowpass (git-backed and versioned) |
| Timeline | published immediately on completion, no embargo |
