The sampling rate should be at least twice the bandwidth of the signal, in order to fully reconstruct the signal.. Husheng Li. The University of Tennessee. AM Signals and Spectra. An AM signal can be written as. Power of AM. The total transmit power is given by. We can prove that, at least 50% (often close to 2/3) of the total transmitted power resides in a carrier term that is independent of the signal and thus conveys no message information. (what a waste!).
