Exp. (b)
Equation of an amplitude modulated wave is given by the relation,
For the given graph,
maximum amplitude,
and minimum amplitude,
From Eqs. (ii) and (iii), we get
and
For angular frequency of message signal and carrier wave, we use a relation
(as from given graph, )
and (as from given graph, )
When we put values of and in Eq. (i), we get
