8.12 SUMMARY

• Sinusoidal steady-state in a dynamic circuit is a state when all the response variables contain only one component with a sinusoidal waveshape that has the same frequency as that of the sinusoidal forcing function applied. The response will, in general, have a phase difference with respect to input. This state will be established only after a transient period that follows the application of sources. Sinusoidal steady-state response in linear circuits obeys superposition principle.
• The real part of the steady-state response to a complex exponential function e^jωt = steady-state response to cosωt and the imaginary part of the steady-state response to e^jωt = steady-state response to sinωt.
