Hi all..Really sorry to bother you... But I got this tutorial and I tried it really hard and I managed to solve every question except the 3rd question..I tried deeply but it only gives me headaches..I'm posting the question below and if anyone of you could help I will be extremely grateful..
A signal x(t) modulates a Narrowband FM (NBFM) transmitter such that the peak phase deviation is 10 degrees. The carrier frequency in 10 MHz.
1. Determine the peak frequency deviation of the FM signal.
2. Evaluate the spectrum of the modulated signal (find an expression) using the narrowband analysis technique.
Fourier representation of the signal,
n = ∞
x(t) = ∑Cn exp(j2Πfmt) where Cn=5exp(jΠn/2)*(sin(nΠ/2)/nΠ/2),fm=message frequen
n = -∞
cy. you may express your answer in terms of Cn.
Can you please add an explanation on how you got the answer too??? thanx very much..
