A single tone burst yields a continuous spectrum while periodic pulses yield line spectra

Evidence

The panel “tone burst” in Fig. 1.1 is the first example of a series of sounds which produce continuous rather than line spectra. The function illustrates a single 2-kHz tone burst of 2-ms duration. The corresponding spectrum shows a maximum at 2 kHz and minima with spacings of 500 Hz. Thus the spectrum of the single tone burst is comparable to the spectra of tone pulses or DC pulses. Although tone pulses and DC pulses produce line spectra, a single tone burst produces a continuous spectrum. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
