A message signal is modulated on a carrier wave of amplitude \$50V\$ using amplitude modulation. The modulation index is given as \$50\%\$. Find the amplitude of the AM wave.
I was able to calculate the amplitude of the message signal as \$25V\$. However I'm stuck at the amplitude of AM wave.
The maximum displacement of the AM wave will be \$50+25=75V\$ and the minimum displacement will be \$50-25=25V\$.
So is the amplitude of the AM wave \$75V\$ or is it \$75-25=50V\$ i.e. is it the maximum displacement or the difference between the maximum and minimum displacements?
I know amplitude is the maximum displacement from the mean position however I can't seem to figure the mean position of this AM wave.
