One More Tool for Understanding Resonance and the Way for a New Definition

The generalized input includes both generator inputs and initial conditions. (This becomes trivial when the Laplace transform is used to transform a system scheme.) Considering the superposition of the output function of a linear system for such an input, we obtain the associated structure of the solution of the linear system in a form that is different from (3). Respectively, the output function is written as ZIR(𝑡) + ZSR(𝑡).
