A `1000 kHz` carrrier is simultaneously modulated with `f_(m1)=300Hz`, `f_(m2)=800Hz` and `f_(m3)=1 KHz` audio sine waves. What will be the frequencies present in the output?
(`a`) `{:(f_(LSB1)=999.7 KHz),(f_(USB1)=1000.3 KHz):}`
(`b`) `{:(f_(LSB2)=999.2 KHz),(f_(USB2)=1000.8 KHz):}`
(`c`) `{:(f_(LSB3)=999KHz),(f_(USB3)=1001KHz):}`
(`d`) `{:(f_(LSB3)=990KHz),(f_(USB3)=1010KHz):}`

A

`a` only

B

`b`, `c` and `d`

C

`a`, `b` and `c`

D

`a`, `c` only

Text Solution

Verified by Experts

The correct Answer is:
C
Frequencies present in the out put are `f_(c)-f_(m)` and `f_(c)+f_(m)`
