A continuous-time periodic signal x(t) is real valued and has a fundamental period T = 8 seconds. The non-zero Fourier series coefficients of x(t) are: a₁ = a_₁ = 2, a3 = a_3 = 4j. Express x(t) in the form x(t) = o ancos (not) =0 ○ a. x(t) = 8 cos(t) + 4 cos(³t+1) O b. x(t) = 4 cos (t) + 8 cos(t+1) x(t) = 4 cos(t) + 8 cos(³t+1) x(t) = 8 cos(3³t) + 4 cos(t+1) ○ c. O d.
