A bandlimited periodic continuous-time signal is sampled at twice its Nyquist rate over exactly one fundamental period at f s = 220 Hz with the first sample occurring at t = 0 and the samples are {1, ? 2, ? 4, 6, 3, 5, 9,7} .
(a) What is the maximum frequency at which the continuous-time signal could have any signal power? (b) What is the fundamental period T 0 of the continuous-time signal? (c) If sample 1 occurs at time t = 0 and the sampling continued indefinitely, what would be the numerical value of sample 317 and at what time would it occur?
