Bandwidth =2 upsilonm (maximum frequency) =2× 6 × 103 Hz =12 KHz

Q. A $1000 k Hz$ carrier wave is modulated by an audio signal of frequency range $600 - 6000 Hz$ . What is the bandwidth of the channel?

$24 k Hz$

$10 k Hz$

$48 k Hz$

$12 k Hz$

Bandwidth $= 2 υ_{m}$ (maximum frequency)
$= 2 \times 6 \times 1 0^{3} Hz$
$= 12 KHz$
