The audio signal used to modulate 60 sin 2 π 10 6 t is 15sin 300 π t. The depth of modulation is Options: A . &nbsp 50% B . &nbsp 40% C . &nbsp 25% D . &nbsp 15% E . &nbsp The frequency of modulated wave varies as frequency of carrier wave

Answer: Option C : C m a = E m E c = 15 60 × 100 = 25 %

The audio signal used to modulate 60 sin 2π106t is 15sin 300π

Question -

The audio signal used to modulate 60 sin 2 $π 10^{6}$ t is 15sin 300 $π$ t. The depth of modulation is

Answer: Option C
:
C

$m_{a} = \frac{E_{m}}{E_{c}} = \frac{15}{60} \times 100$ = 25 %
