41. a{n} = 2-(nT) sin (2x(100)n,55) ~ s(F) 4.2. The discrete-time sequence an fn] = coal) results by sampling the contimuous-time signal z(t) = cs(Cez). Since w = MT and T = 1/1000 seconds, the signa) frequency could be: 2, = 5 +1000 = 2508 or possibly: / 2, = (22 +5) 1000 = 22507. 4.3. {a) Since z[n} = z.(nT), - = = 4000mnT a T = F000 (b) No. For example, since (En) = cost Zn) maak gy = cosh T can be 7/1200. 4.4. (a) Letting T = 1/100 gives 2[n) = 2.{nT) . 1 1 = sin (20955) + cos (som) fe arn = sa(F) +em(3*) (b} No, another choice is T = 11/100: =p] 2-{nT} = ain (200035) + cos (son s55) - #(22)-=(&F) - =(B)-=(%) 4.3.
