    Hi,


    In amplitude modulation,the signal m(t) is modulated over the carrier to get packets .but insted why dont we simple do s(t)=Ac*cos(wt)+m(t) to get the a wave that is periodically clamped with respect to m(t),all we need a high freq. carrier and this does the job.please tell me why is not used and why a packet wave is chosen.

    Thank you.
