In amplitude modulation, sinusoidal carrier frequency used is denoted by `omega_(c)` and the signal frequency is denoted by `omega_(m)`. The handwidth `(Deltaomega_(m))` of the signal is such that `Deltaomega_(m)ltltomega_(c)`. Which of the following frequency is no =t contained in the modulated wave.A. `omega_(m)+omega_(c)`B. `omega_(c)-omega_(m)`C. `omega_(m)`D. All of these |

Answer» Modulated wave has three frequencies `(omega_(m)+omega_(c)),omega_(c)` and `(omega_(c)-omega_(m))` It means `omega_(m)` is exluded. Thus option (c) is true. |
