MCQ

In an FM system a $7 \mathrm{kHz}$ signal modulates $108 \mathrm{MHz}$ carrier so that frequency deviation is $50 \mathrm{kHz}$. The carrier swing is

✓
$7.143$
B
$8$
C
$ 0.71$
D
$350$

✓

Answer

Correct option: A.

$7.143$

Carrier swing $=\frac{\text { Frequency deviation }}{\text { Modulatingfrequency }}=\frac{50}{7}=7.143$
