(i) Draw the plot of amplitude versus `omega` for an amplitude modulated were whose carrier wave `(omega_(c))` is carrying two modulating signals, `omega_(1)` and `omega_(2)` `(omega_(2) gt omega_(1))`. (ii) Is the plot symmetrical about `omega_(c)` ? Comment especially about plot in region `omega lt omega_(c)`. (iii) Extrapolate and predict the problems one can expect if more waves are to be modulated. (iv) Suggest solutions to the above problem. In the process can one understand another advantage of modulation in terms of bandwidth?
