The frequency response curve (as shown in figure below) 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
All of these
Answer
All of these
Explanation
Solution
: Bandwidth of AM wave should be
2ωm=(ωc+ωm)−(ωc−ωm)
It is applicable for case (i), (ii) and (iii)
The case (iv) will reject the required signal for AM waves
