Question 3 (a) Let a signal x(t) = 7sin (11nt), be sample at the rate of fe to obtain x[n] expressed as: x[n] = Acos (21tfon + o), Then determine Α, φ, fo, 1) If sampling frequency is 10 samples/sec 2) If sampling frequency is 5 samples/sec 3) If sampling frequency is 15 samples/sec (b) Suppose, *[n] = 2.2cos (0.31 - ), is obtained by sampling x(t) = A cos (2 fot+) with sampling frequency as 6000 samples per second. Determine (the mathematical formula for) three continuous time signals that could have produced x[n] (with each signal having frequency less than 8 kHz). /
