z2gamma

Convert impedance to reflection coefficient

Syntax

gamma = z2gamma(z)
gamma = z2gamma(z,z0)

Description

gamma = z2gamma(z) converts the impedance z to the reflection coefficient gamma using a reference impedance of 50 ohms.

gamma = z2gamma(z,z0) converts the impedance z to the reflection coefficient gamma using a reference impedance of z0 ohms.

Examples

collapse all

Convert an impedance of 100 ohms into a reflection coefficient, using a 50-ohm reference impedance

z = 100;
gamma = z2gamma(z)
gamma =

    0.3333

Algorithms

z2gamma calculates the coefficient using the equation

Γ=ZZ0Z+Z0

Introduced in R2008a
