A message signal of freuency `omega_(m)` is superposed on a carrier wave of frequency `omega_(c)` to get an amplititude modulated wave (AM). The frequency of the AM wave will be

Options

A. `omega_(m)`
B. `omega_(c )`
C. `(omega_(c ) + omega_(m))/(2)`
D. `(omega_(c ) - omega_(m))/(2)`

Answer

B

Explanation

Here, according to the question, frequency of carrier wave is `omega_(c )`.
Thus the amplitude modulated wave also has frequency `omega_(c )`.
