In this experiment pulses and their spectrum are directly shown. You can change the pulse shape and see how the corresponding spectrum looks like.
Start the simulation. A Gaussian Pulse is pre-selected and its spectrum is directly shown on the spectrum analyzer.
To change the pulse shape select the pulse of your choice from the drop down menu in the ‚??Pulse - select system‚?? window.
Do you know how the spectrum of a sinc-pulse looks like? Go on and try the other pulse shapes.
Also take a look at the other simulation apps to get further into signals and spectra.
