Tardigrade Admin · Accepted Answer

Carrier wave frequency V C =(100 π/2 π)=500 Hz Modulating wave frequency V m =(4 π/2 π)=2 Hz ∴ V C - V m , V c , V c + V m =498 Hz , 500 Hz , 502 Hz

Q. The amplitude of $15 sin (1000 π t)$ is modulated by $10 sin (4 π t)$ signal. The amplitude modulated signal contains frequency (ies) of
A. $500 Hz$
B. $2 Hz$
C. $250 Hz$
D. $498 Hz$
E. $502 Hz$
Choose the correct answer from the options given below:

B Only

A and B Only

A, D and E Only

A Only

Carrier wave frequency
$V_{C} = \frac{100 π}{2 π} = 500 Hz$
Modulating wave frequency
$V_{m} = \frac{4 π}{2 π} = 2 Hz$
$∴ V_{C} - V_{m}, V_{c}, V_{c} + V_{m}$
$= 498 Hz, 500 Hz, 502 Hz$
