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)(ωcωm)2\omega_{m} = (\omega_{c} + \omega_{m}) - (\omega_{c} - \omega_{m})

It is applicable for case (i), (ii) and (iii)

The case (iv) will reject the required signal for AM waves
