The frequency response curve (figure) for the filter circuit used for production of AM wave should be

Options

A. i followed by ii
B. ii followd by i
C. iii
D. all of these

Answer

D

Explanation

Bandwidth of AM wave should be
`2omega_(m)=(omega_(c)+omega_(m))-(omega_(c)-omega_(m))`
it is applicable for case (i),(ii) and (iii)
The (iv) will reject the required signal for AM waves.
