An FM signal is given as;
Where m(t) is shown in the figure given below.
It is given that carrier frequency (f_{c}) is 1000kHz. Then calculate the value of instantaneous frequency (f_{i}) at t = 1.5 sec and the peak frequency deviation (δf) of the above FM signal.
A phase modulated wave can be generated from frequency modulator by connecting a ___________ before the modulator and a frequency modulated wave can be generated from phase modulator by connecting a __________ before the modulator.
Frequency modulated signal with single tone modulation has a frequency deviation of 20 kHz and bandwidth of 60 kHz. The frequency of the modulating signal will be 
In a frequency modulation system, maximum frequency deviation allowed is 1000 and modulating frequency is 1 kHz. Determine modulation index β.
The four basic elements in a PLL are loop filter, loop amplifier, VCO and
Determine the bandwidth required for an FM signal having frequency 2 kHz and maximum deviation 10 kHz.
Consider the FM signal x_{c}(t) = 10 cos(2π × 10^{8}t + 0.5 sin(10^{4} πt)). The bandwidth of x_{c}(t) is approximately
