Abstract
The options to compute, display, and describe the frequency spectrum are reviewed. This includes the use of different frequency and amplitude scales, the automatic detection of frequency peaks in particular the fundamental frequency peak and the dominant frequency peak, the identification of harmonics series, the principle of symbolic aggregate approximation, and the use of other spectrum parametrizations. The quefrency cepstrum and the phase portrait are also introduced.
