The Fourier analysis component performs a Fourier analysis of the input signal over a running window of one cycle of the fundamental frequency of the signal.

The output is held constant to the Initial magnitude and Initial phase values for one cycle of the specified fundamental frequency connected to the second input of the component.

Internal Circuit of the Component

Example Model

This example demonstrates the use Fourier block to compute the fundamental magnitude and angle of a signal with harmonics.

Note that the following demo requires that users edit the ScopeView template, and replace the existing .oprec data source with the data generated during the simulation
