Contents • Load Example Data • Quick view of double-sided (two-sided) magnitude spectrum • Double-sided magnitude spectrum with frequency axis (in bins) • Single-sided magnitude spectrum with frequency axis in bins • Single-sided magnitude spectrum with frequency axis in Hertz • Single-sided magnitude spectrum with frequency axis normalised • Single-sided magnitude spectrum – frequency in rads per sample • Double-sided magnitude spectrum showing negative frequencies • Single-sided magnitiude spectrum in decibels and Hertz • Single-sided power spectrum in decibels and Hertz • Single-sided power spectrum in dB and frequency on a log scale
