Formula and methodology
Formula: Reflection coefficient Γ=(load−source)/(load+source); voltage transfer fraction = load/(source+load).
The two outputs distinguish a matched resistive pair from the load-voltage fraction of a Thevenin source.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Source resistance — Ω; minimum 1.0E-6; maximum 1000000000
- Load resistance — Ω; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Source resistance | 50 |
| Load resistance | 50 |
Reflection coefficient = 0; voltage transfer = 0.5.
Assumptions and limits
- Both resistances are positive real values and the source-load connection is resistive.
- The source voltage is normalized out of the voltage-transfer fraction.
- Reactive impedance, frequency, transmission-line length, noise, and power ratings are not modeled.
