In a circuit with multiple input functions acting simultaneously, the superposition
principle is applicable only for the forced response component. Transient response does not
go by the superposition principle.
Concept-16
A more powerful way to partition the total response in a circuit is in terms of the
zero-input response and the zero-state response. Total response is the sum of the two. Zero-
input response is the response of the circuit if xis held zero for all t≥0. Zero-state response
is the total response to x applied from t 0 onwards, with the circuit initially relaxed (i.e.,
all initial conditions at zero) at t 0.
Zero-state ...
