The AM wave contans three frequencies viz:

A

`(f_(c))/2,(f_(c)+f_(s))/2,(f_(c)-f_(s))/2`

B

`2f_(c),2(f_(c)+f_(s)),2(f_(c)-f_(s))`

C

`f_(c),(f_(c)+f_(s)),(f_(c)-f_(s))`

D

`f_(c),f_(c),f_(c)`

Text Solution

Verified by Experts

The correct Answer is:
C
`C_(m)(t) =(A_(c)+A_(m) sin omega_(m)t)sin omega_(c)t`
`=A_(0) sin omega_(0)t +(muA_(0))/2 cos (omega_(o)-omega_(m))t`
`-(muA_(0))/2cos (omega_(c)+omega_(m))tt`

Both amplitude modulation (AM) and frequency modulation (FM) are used for radio broadcasting. The amplitude of the high frequency carrier wave is varied or modulated in accordance with the variations in the amplitude of the audio signals that are to be transmitted, in te process of amplitude modulation in frequency modulation te amplitude of the carrier remains constant but its frequency is varied inn accordance withh the audio signal. Reception with AM signals is in general is affected by interference of various kinds ad elaborated equipment is required for FM broadcast. A radio frequency carrier wave can be modulated using a-
