at a specified fundamental frequency, with a simulation time independent of the time constants of the circuit. The PSS analysis also determines the circuit's periodic operating point which is required starting point for the periodic time-varying small-signal analyses: PAC, PSP, PXF, and Pnoise. The PSS analysis works with both autonomous and driven circuits. PSS is usually used after

transient analysis A system is said to be transient or in a transient state when a process variable or variables have been changed and the system has not yet reached a steady state. The time taken for the circuit to change from one steady state to another steady sta ...

Examples

The current through a capacitance of value C in time domain is

i(t)= C \frac

, which becomes

v(t) = v(t_0) + \frac\int_^

. For this component operating in a periodic steady state circuit, its voltage will be

v(t_0 + T) = v(t_0)

when T is equal to its fundamental period. Referring back to the original voltage function

v(t) = v(t_0) + \frac\int_^

, it can be determined that the average current flowing through the capacitor is zero in periodic steady state. Electricity {{electronics-stub
