ϕ 2 (t; t 0 ) = rq 1 (t; t 0 )
for any t ≥ t 0 .
Example 5.9 An ideal operational amplifier operating in the linear region is a
resistive two-port networks satisfying in the (v, i)-domain (Fig. 5.15)
v 1 (t) = 0
i 1 (t) = 0.
In the (ϕ, q)-domain we still have a resistive two-port networks described by
ϕ 1 (t; t 0 ) = 0
q 1 (t; t 0 ) = 0
for any t ≥ t 0 .
