5-Only drawings ! For the system in belove x(t) = input y(t)=output,
below first shape
X(f), Fourier transform of x(t) showed above. H1(f) and H2(f) are filters that represented belove.
below second shape
a) Draw the u (f) sign, which is the form of X (t) after being modulated with the 2cos (2150t) carrier sign in frequency environment.
b)Draw the v (t) sign, which is the form of the modulated u (f) sign after passing through the H (f) filter in frequency environment.
c)Draw the w (f) sign, which is the form of v (f) after demodulation with the 2cos (2150t) carrier sign in frequency environment
d)Draw the y (f) output signal, which is the state of demodulated w (f) after passing through the Hz (f) filter in the frequency environment. Note: To remind the frequency shift feature; F [w (t) cos (2nfet)] = ((W (f - fe) + W (f + f)]
