Two Port Networks

An electrical network with two separate ports for input and output.

Port

A pair of terminals through which current may enter or leave a network.

Z parameters

Denoted by . Aka. open-circuit impedance parameters.

Y parameters

Denoted by . Aka. short-circuit admittance parameters.

Transmission parameters

Here:

• and are dimensionless
• is in Ohms
• is in Siemens

The values can be evaluated by setting:

Reciprocal network

A network is said to be reciprocal if .
