Periodic spectra show discrete partials spaced inversely to period
Evidence
Thus the main difference between the spectrum of periodic and aperiodic waveforms is that periodic waveforms have discrete partials, which can be represented as lines in the spectrum with a spacing that is inversely proportional to the period of the 7F Hz 5F Hz 3. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 460
