Nyquist / Wien Bridge Oscillator Frequency Calculator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Effect

Computation or source lookup only

Input and validation requirements

The formula produces an undefined result when R=0, so the instrument must explicitly reject zero-valued component inputs. Unit-prefix ambiguity can also produce a million-fold frequency error if kΩ and nF are stripped or misinterpreted.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.
