Question

A message signal of frequency ${\omega }_m$ is superposed on a carrier wave of frequency ${\omega }_e$ to get an amplitude mediated wave (AM). The frequency of the AM wave will be

• A. ${\omega }_m$
• B. ${\omega }_e$
• C. $\frac{{\omega }_e+{\omega }_m}{2}$
• D. $\frac{{\omega }_e-{\omega }_m}{2}$

Answer 1

The correct option is C $\frac{{\omega }_e+{\omega }_m}{2}$

$frequencyofAMwaveis\frac{w_a+w_m}{2}$

$Hence,theoptionCisthecorrectanswer.$
