Linear modulations are characterized by a bandwidth amplitude B which is equal to the modulation signal. AM is a linear modulation the modulated and the modulating signal present the same bandwidth amplitude centered respectvely on the carrier frequency and the zero frequency. Furthermore the modulation does not affect the spectral content of the modulating signal: the ratio between two harmonic components of the modulating signal is leaved unchanged by the modulation.

Non linear modulation act as nonlinear system: the bandwidth of the modulated signal is wider and can be alterated in terms of ratio between two spectral components with respect to the modulating signal.
