Understand Zero Initial Condition in Linear Systems

[willisfang]

Can anyone tells me what is exactly
"Zero initial condition" in time-invariant passive linear system?

thanks a lot.

I would guess that it just means that all nodes start off discharged.

Zero initial condition means that all capacitors have zero initial voltage and all inductors have zero initial current, so no energy is stored in the circuit. In that way, the behaviour of the circuit depends uniquely on the inputs.
