  • two-port parameter;
  • conversion;
  • wave parameter


Conversion between the z, y, h, and g two-port voltage-current parameters is simply rearrangement of two linear equations relating voltages and currents at the two ports. Converting between these and the S parameters requires relating the voltage waves to voltages and currents. This latter relationship always includes the characteristic impedance, Z0, by which the S parameters are defined.

The definitions of the various two-port parameters are described. In each case it is assumed that the current is flowing into the port terminal.
