Enter a 2-port in any of the five standard forms (Z, Y, h, g, ABCD). The page computes the other four live, checks reciprocity and symmetry, and visualizes a candidate T-network. Formulas verified against Sadiku §19.
Input form
Z parameters (open-circuit impedance)
V₁ = Z₁₁·I₁ + Z₁₂·I₂ V₂ = Z₂₁·I₁ + Z₂₂·I₂

Test networks
Click a preset to load its Z parameters. Then switch the form tabs to see how the same network looks in Y, h, g, ABCD.
Schematic (T-network candidate)
Approximated from Z₁₁, Z₁₂, Z₂₂: Z_a = Z₁₁ − Z₁₂, Z_b = Z₁₂, Z_c = Z₂₂ − Z₁₂. Other forms may not be realizable as a T-network.
