1/23/2024 0 Comments Bode plot in multisim![]() ![]() AC Analysis is used to calculate the small-signal response of a circuit. In AC Analysis, the DC operating point is first calculated to obtain linear, small-signal models for all nonlinear components. This presentation provides a basic introduction to Bode plots and explains how Bode plots can be used with an oscilloscope to evaluate power supply feedback. Repeat all the above steps (Multisim analysis, building the actual circuit, Bode plot. Then, the equivalent circuit is analyzed from a start to a stop frequency. 1) Open Multisim: Start > Engineering > NationalInstruments >Multisim. ![]() 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. ![]()
