If the Function Generator is set to a square or triangular waveform, it will automatically switch internally to a sinusoidal waveform.All input sources are considered to be sinusoidal, their frequency is ignored.Nonlinear components are represented by linear AC small-signal models, derived from the DC operating point solution.AC sources, capacitors, and inductors are represented by their AC models.

Multisim constructs this matrix using the following approach:

Then, the equivalent circuit is analyzed from a start to a stop frequency.

In AC Analysis, the DC operating point is first calculated to obtain linear, small-signal models for all nonlinear components. AC Analysis is used to calculate the small-signal response of a circuit.
