- Open a new Simulink model.
- From the Simulink Library Browser, open the "DSP System Toolbox" library.
- Drag the "FFT" block into the model.
- Connect the input signal to the "FFT" block.
- Set the FFT length parameter to desired number of samples. This should always be a power of 2.
- Connect the output of the "FFT" block to a "Spectrum Analyzer" block, which can be found in the "DSP System Toolbox" library. This block will display the frequency spectrum of the input signal in real-time.
- Configure the "Spectrum Analyzer" block as needed to set the frequency range, sample rate, and other parameters of the display.
