The spectral component of noise associated with kth frequency is given, in the limit as Δf → 0 by nk(t) written as nk(t) = Ck cos (2πk Δft + θk) Consider the following statements as regards Ck and θk 1. Ck and θk are independent of one another2. Ck and θk are independent of the amplitude of a spectral component at a different frequency3. Ct and θk are independent of the phase of a spectral component at a different frequency Which of the above statements are correct?

• B. 1, 3 only
• C. 1, 2, 3
• D. 2, 3 only
