A) 0.05 and \[1\pm 0.010\text{ }MHz\]
B) 0.5 and \[1\pm 0.010\text{ }MHz\]
C) 0.05 and \[1\pm 0.005\text{ }MHz\]
D) 0.5 and \[1\pm 0.005\text{ }MHz\]
Correct Answer: A
Solution :
[a]: Modulation index, \[\mu =\frac{{{A}_{m}}}{{{A}_{c}}}\] \[\mu =\frac{0.5V}{10V}=0.05\] The side bands frequencies are\[{{\upsilon }_{SB}}={{\upsilon }_{c}}\pm {{\upsilon }_{m}}\] \[=(1\pm 0.010)MHz\]
