WOLFRAM SYSTEM MODELER
SeriesCircuitA circuit using an external chirp signal |
SystemModel["IntroductoryExamples.ExternalFunctions.SeriesCircuit"]
This model uses chirp source to test the resonance frequencies of an electrical circuit.
Simulating the model for 10 seconds gives a peak current at 5 seconds:
As the input frequency is swept from 0 to 1000 rad/s during this period, this corresponds to a resonance frequency of 500 rad/s:
This can also be verified by calculating the resonant frequency for the circuit analytically:
Of course for more complicated systems it might be difficult to calculate the resonant frequency analytically, and in these cases a chirp signal can be very useful.
