Q1:

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 (2pk Δft + θk)
Consider the following statements as regards Ck and θk
  1. Ck and θk are independent of one another
  2. Ck and θk are independent of the amplitude of a spectral component at a different frequency
  3. Ct and θk are independent of the phase of a spectral component at a different frequency
Which of the above statements are correct?

A 1, 2 only

B 1, 3 only

C 1, 2, 3

D 2, 3 only

ANS:C - 1, 2, 3
