21. An AM signal has a carrier frequency of 3MHZ and an amplitude of 5V peak. It is modulated by a sine wave with a frequency of
500HZ and a peak voltage of 2V. Write the equation for the signal.
A
v (t) =[5+2sin (3.14x10r) ]sin (18.85x10t)
B
v (t) =[3+5sin (5.18x101) ]sin ( 17.56x°t)
v (t) = [2+ 10sin (8.14x10t) ]sin ( 16.85x10t)
no answer
