  Compensation Theorem 5.19

Substitution Theorem

Let a circuit with unique solution be represented as interconnection of two networks N

1

and N

2

and let the interaction between N

1

and N

2

be only through the two terminals at

which they are connected. N

1

and N

2

may be linear or non-linear. Let v (t) be the voltage

that appears at the terminals between N

1

and N

2

and let i(t) be the current flowing into

N

2

from N

1

. Then, the network N

2

may be replaced by an independent current source of

value i (t) connected across the output of N

1

or an independent voltage source of value

v(t) connected across the output of N

1

without affecting any voltage or ...
