PPT-Chapter 4. Amplitude Modulation

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 23 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.
