(a) Let, x(t) = 10 + 20 cos (214(100)t + 5) + 10 cos(21(250)) 1) Use Euler's relation to express the signal in the following form N X(t) = X, +1 Xxeirasol izrkkot COS (b) If 2) Find wo, and X R 3) Plot the spectrum of this signal x(t) is defined as: x(t) = [12 + 7 sin (nt - ) cos (13tt) Using phasors-form of complex numbers, show that x(t) can also be expressed as: x(t) = A, cos(Wit + 1) + Ay cos(wat + 2) + Az cos(W3t+03)
