For each of the following signals, determine whether it is periodic, and if it is, find the fundamental period: (a) x(t) = cos (2nt) (b) x(t) = sin'(2t) (c) x(t) = e" cos(2mt) (d) x[n] = (-1)" (e) x[n] = (-1) (f) x[n] = cos(2n) (g) x[n] = cos(2rn) %3D %3D Problem 1.1 Find the even and odd components of each of the following signals: (a) x(t) = cos(t) + sin(t) + sin(t) cos(t) (b) x(t) = 1 + t + 3t2 + St3 + 9t* (c) x(t) = 1 + t cos(t) + t sin(t) + t' sin(t) cos(t) (d) x(t) = (1 + t') cos (10t) %3D
