Sound signals and sound curves
Periodic and aperiodic sound signals are explained and associated oscilloscope curves are shown.
Aperiodic tones on the contrary are composed of many individual vibrations, the frequencies of which are not in integral relation to each other. The examples of noise and bang are used to explain this further.
Information and ideas:
The media used in the information sheet are available as individual media files on the media portal of the Siemens Stiftung.
