QUESTION 1 Problem 1: A continuous-time signal xc (t) = 2sin(25πt) + sin(15πt) + 4 sin (20лt) + 2 sin (30nt) + 3 sin(35nt) is sampled at a rate of 25 samples/s and then passed through a perfect D/A converter to produce the analog signal ye(t). (a) Identify which terms in xc (t) are aliased. (b) Find y(t).
