The condition for successful AM modulationdemodulation is a

The condition for successful AM modulation/demodulation is

a) omega subscript c greater than omega subscript m

b) omega subscript c greater than 0

c) omega subscript c greater than 2 omega subscript m

d) omega subscript c greater than 3 omega subscript m

e) None of the above.

Note:C and D are not correct.

its is option a....

for propoer modulation Wc>Wm .other wise spectrum may overlap on each other.

it is only option A but not C/D because Wc>Wm but it should not be greater then by any multiplication factor
