^{}### AC Circuit Analysis- Time to Frequency Domain Conversion

Converting a circuit from the time to the frequency domain is only done for AC circuits since AC circuits are the only circuits in which the power source has a frequency that is greater than 0 Hz. In DC circuits the frequency of the source is 0 Hz. Therefore reactive components such as capacitors and inductors are neutral so there would be no need to analyze it in the frequency domain

^{}### Thevenin Equivalent and Norton Equivalent Circuits

Finding the Thevenin Equivalent Circuit by Simulation. The examples above illustrated how to solve for the Thevenin equivalent voltage and resistance by hand and by using a DC Sweep simulation over the test current value to measure the slope of the V-I curve.

^{}### Partial element equivalent circuit - Wikipedia

A 10x10x10 cm cube is modelled in the frequency domain. The cube is excited with a unitary current pulse in one corner. A 19x43x38 cm LxWxT case with one opening 19x10 in the front is modeled in the time domain. Partial element equivalent circuit method PEEC is partial inductance calculation used for interconnect problems from early 1970s which is used for numerical modeling of
