Problem 5.2 For each time domain signal z(t) below, find its Fourier transform Â(ƒ) = X(j2f) and sketch the magnitude (f). It is often helpful to sketch z(t) first. (a) r(t) = 4sinc(3t - 2). (b) x(t)=51-3,2] (t). (c) r(t) = -41-3,-2) (t) + 2t1-2,2] (t) + 41(2,3] (t). Hint: Differentiation may be helpful. (d) x(t) = 38(t2) - 8(t-4). (e) x(t) = 3 cos(60nt+)-4 sin(70nt +)-2 (No need to sketch z(t) in this part.) (f) r(t) = sinc(3t)sinc(4t).

Problem 5.2 For each time domain signal x(t) below, find its Fourier transform Â(f) X(j2f) and sketch the magnitude |Â(ƒ)]. It is often helpful to sketch r(t) first. (a) r(t) = 4sinc(3t - 2). (b) x(t) = 51-3,2] (t). (c) x(t) = -41-3,-2) (t) + 2t1-2,2] (t) + 41(2,3] (t). Hint: Differentiation may be helpful. (d) x(t) = 38(t2) - 6(t-4). (e) r(t) = 3 cos(60nt+)-4 sin(70nt +)-2 (No need to sketch r(t) in this part.) (f) r(t) = sinc(3t)sinc(4t). =
