For all discrete sinusoidal pairs, determine whether all signals have the same sample value?

a) x1 [n] = 2 cos (0.5 an + 0.1 x), X2 [n] = 2 cos (1.5 în - 0.17); b) x1 [n] = X2 [n] = 2 cos (0.8 an + 0.1 7). %3D 2 cos (2.8 An + 0.1 x),

Expert Solution
Step 1

It is given that:

a)x1n=2cos0.5πn+0.1πx2n=2cos1.5πn-0.1πb)x1n=2cos2.8πn+0.1πx2n=2cos0.8πn+0.1π
