hi,
we are aware that in frequency modulation, frequency of carrier is made proportional to message signals (without adding any constant term). Similar are the principles of phase modulation, angle modulation. Now in this array of concepts, does amplitude modulation not stand out as an exception?
In this case, we are modifying the amplitude of carrier(as per the message signal) and then we add the term Acos(wt) where w is the carrier frequency to this changed carrier. Many research papers call it a DSB-LC modulation. Don't you think that was the better terminology to be used than amplitude modulation.
