The frequency response curve (figure) for the filter circuit used for production of AM wave should be A. (i) followed by (ii)B. (ii) followed by (i)C. (iii)D. (iv)

Answer» Correct Answer - A::B::C
Here, for the production of amplitude modulated wave, bandwidth is given by = frequency of upper side band - frequency of lower side band
`=omega_(USB)-omega_(LSB)=(omega_(c)+omega_(m))-(omega_(c)-omega_(m))`
