Unformatted text preview: 3. Consider the following sampling and reconstruction configuration: The output y(t) of the ideal reconstruction can be found by sending the sampled signal x s (t)=x(t)p(t) through an ideal lowpass filter with the frequency response function. x(t) Sample at T Ideal reconstruction x[n] y(t) 10 0 10 x(w) w 1 2 10 0 10 x(w) w 1 Let x(t)=2+cos(50πt) and T = 0.01sec (a) Draw  X s (w) , where x s (t)=x(t)p(t) . Determine if aliasing occurs. (b) Determine the expression for y(t) 4. Repeat Problem 3. for x(t)=2+cos(50πt) and T = 0.025sec. 0 T 0.5 w s 0.5 w s...
