Question

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 1

Answer: (D)

All of these

Answer 2

: Bandwidth of AM wave should be

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

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

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