gamma2z

Convert reflection coefficient to impedance

Syntax

z = gamma2z(gamma)
z = gamma2z(gamma,z0)

Description

z = gamma2z(gamma) converts the reflection coefficient gamma to the impedance z using a reference impedance Z0 of 50 ohms.

z = gamma2z(gamma,z0) converts the reflection coefficient gamma to the impedance z by:

  • Computing the normalized impedance.

  • Multiplying the normalized impedance by the reference impedance Z0.

Examples

collapse all

Calculate impedance from given reference impedance and reflection coefficient values

z0 = 50;
gamma = 1/3;
z = gamma2z(gamma,z0)
z = 100.0000

Algorithms

The following equation shows this conversion:

Z=Z0*(1+Γ1Γ)
