1.)
The shorter a pulse is in the time domain, the broader its spectrum in the frequency domain.
The picture above illustrates how Fourier's first principal comes into play.
2.)
Sharp corners in the time domain translate to high harmonics in the frequency domain.
The picture bellow illustrates how Fourier's second principal.
