A single tone message signal, m(t) = 2 cos(211 X 1000 t), (freq. is in Hz) is applied to an FM modulator with the following parameters: Amplitude of the Carrier = 10 (V), Carrier Frequency = 100 (kHz), Frequency sensitivity factor = kx = 103 (Hz/Volt). The modulated signal s(t) is passed through a bandpass filter centered at 102 (kHz) with a bandwidth of 3(kHz), and the output signal sf(t) is obtained. (a) Express the output of the filter, sf(t)...
a. For the wideband FM signal given by SFM(t) = cos[2πfct+ 3sin2π25t]
a. For the wideband FM signal given by SFM(t) = cos[2πfct+ 3sin2π25t], draw only positive side of the spectrum, (from n=-5 to n=+5). Assume the carrier frequency (fc) of 1 KHz. Hint: First calculate β by comparing the signal with SFM(t) equation b. The FM signal of part (a) is passed through a bandpass filter centered at 1 KHz with a bandwidth of 210 Hz, as shown below. Draw the new spectrum and calculate the bandwidth and power of the filtered FM...
