A carrier signal with a frequency of 100 MHz, frequency by band limited information sign with 2 KHz
modulating. Maximum frequency deviation of the FM sign (Δf) 25 KHz and information sign amplitude (Am) If it is 15.7 Volts;
a) Calculate the bandwidth of the FM sign?
b) The bandwidth of the FM signal is doubled and the frequency modulation constant is taken if kf = 10000
What can be said about the signal to noise ratio (SNR) of the signal, why?
