It is a continous band of all frequencies from 0Hz up to the highest
frequency which is necessary to create the edge. Depending on how the pulse
is shaped and whether there is a remaining DC offset (step pulse) the
highest amplitude can be found anywhere in the spectrum and the spectrum
might be not continously in- or decreasing.
So basically any single pulse contains infinitly much different excitation
frequencies.=20
