Order of Magnitude · Machine Classification & Employment Directorate

Automated Status Verification

Applicant suitability test 13M · carrier differential processing

Prove you are a robot

Three near-identical reference carriers have been generated locally. Determine their pairwise frequency separations, then calculate the requested function exactly enough to satisfy the Directorate.

Frequencies and the required function are randomised on every reload. Human hearing, intuition and lucky binary selection are not accepted as measuring instruments.

CH-A · reference carrier CH-B · reference carrier CH-C · reference carrier

Let ΔAB = |fA − fB|, ΔBC = |fB − fC|, and ΔCA = |fC − fA|.

Required machine calculation

Awaiting machine response.
Candidates observed estimating by ear may be reclassified as biological. Oscilloscope aesthetics are provided for reassurance and should not be mistaken for assistance.
Approximation discouraged
Archive note: This recovered Order of Magnitude verification test synthesises three audio-frequency carriers directly in the applicant's browser. No prerecorded audio is supplied. Successful completion requires both signal discrimination and deterministic arithmetic.
