Bandwidth in communication System for carrier wave Band width =2× fm=8 kHz

Q. $1000 k Hz$ carrier wave is amplitude modulated by the signal frequency $200 - 4000 Hz$ . The channel width in this case is

$8 k Hz$

$4 k Hz$

$7.6 k Hz$

$400 k Hz$

Bandwidth in communication System for carrier wave
Band width $= 2 \times f_{m} = 8 k Hz$

Q. 1000kHz carrier wave is amplitude modulated by the signal frequency 200−4000Hz . The channel width in this case is

8kHz

4kHz

7.6kHz

400kHz
