Therefore:

Veq = I Req
Vo = n Veq
And:

Table 6.
contains the results of calculations made with these equations. The numbers show that output pulse amplitude
is within millivolts of the nominal values of 2.37V and 3.00V specified by ITU G.703 for 75W and 120W operation. Also,
the 1:2 ratio transformer provides an almost-perfect match for 75W operation, and return loss is well within the ETSI
specification for the 120W load.
