Two-Port Parameter Conversion

D.1

TWO-PORT VOLTAGE AND WAVE PARAMETERS

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 dened. Typically this value is 50 . Table D.1 shows this conversion. The program PARCONV is basically a code of many of the conversions in Table D.1. The denitions of th
