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: A complex matrix, containing both real and imaginary components is created.DC operating Point Analysis is performed to obtain the small-signal models.Multisim performs AC Analysis using the following process: The result of an AC Analysis is displayed in two parts: gain versus frequency and phase versus frequency. 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.
