A communication system uses rectangular pulses \( p(t) \) shown below to represent information. a) Determine the Fourier Transform \( P(j \omega) \) and sketch its magnitude. b) The pulse \( p(t) \) is modulated by a carrier \( c(t)=\cos (2 \pi 10 t) \). Determine and sketch the spectrum of the modulated signal \( x(t)=p(t) c(t) \)
