z2gamma

Convert impedance to reflection coefficient

Description

example

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

Input Arguments

collapse all

Impedance value, specified as a positive scalar.

Data Types: double

Reference impedance, specified as a positive scalar.

Data Types: double

Output Arguments

collapse all

Reflection coefficient, returned as a M element complex vector.

Algorithms

z2gamma calculates the coefficient using the equation

Γ=ZZ0Z+Z0
