Question 1
Direction: In an FM system message signal is m(t) = 10 sin c(400t) and carrier is c(t) = 100 cos2π fct. The modulation index is 6
The expression for the modulated signal is
Question 2
Direction: In an FM system message signal is m(t) = 10 sin c(400t) and carrier is c(t) = 100 cos2π fct. The modulation index is 6
The maximum frequency deviation of the modulated signal is
Question 3
Direction: In an FM system message signal is m(t) = 10 sin c(400t) and carrier is c(t) = 100 cos2π fct. The modulation index is 6
The power content of the modulated signal is
Question 4
Direction: In an FM system message signal is m(t) = 10 sin c(400t) and carrier is c(t) = 100 cos2π fct. The modulation index is 6
The bandwidth of the modulated signal is
Question 5
Direction: An angle modulated signal is given as x(t) =100 cos (2πfct+4 sin 2πfmt)
Where fc =1000 MHz and fm =1000 Hz
If this is an FM signal, the modulation index and the transmitted signal bandwidth is
