P-4.1 Let x (t) = 11 cos(7лt - π/3). In each of the following parts, the discrete-time signal x[n] is obtained by sampling x (t) at a rate f, samples/s, and the resultant x[n] can be written as x[n] = A cos(@₁n + p) For each part below, determine the values of A, p, and ₁ such that 0 ≤ ≤n. In addition, state whether or not the signal has been over-sampled or under-sampled. (a) Sampling frequency is f = 9 samples/s. (b) Sampling frequency is fs = 6 samples/s. (c) Sampling frequency is fs = 3 samples/s.
