###### Question:

Consider the discrete time system given by the difference equation y[n] + ky[n – 1] - áy[n – 2] = 2v[n] + v[n – 1). Suppose that the output signal is given by y[n] = 1 cos(in – m). Then the input signal is v[n] = cos(an – M) v[n] i cosan-5) Ov[n] = 14 cos(Tn) O none of the other answers Ov[n] = cos(an) v[n] = cos(An - )
