The spectrum of the AM signal consists of the original carrier plus the spectrum of the input signal translated to f_c.

Question

Quizplus · Accepted Answer

This is true according to the equation for an amplitude modulated signal, where fS1 is the frequency of the carrier, U1 is the modulation index, B1 is the frequency of the input signal, and B0 is the DC component. The resulting spectrum will be the sum of the original carrier frequency plus the frequency components of the input signal shifted by f_{and f}.
