An exponential signal, x(t) = 4e-2t , is sampled at a frequency of 10 Hz, beginning at time t = 0.
(a) Express the sampled sequence, x[n], up to the fifth term.
(b) If the signal is delayed by 0.2 s, what would now be the first five terms?
(c) What would be the resulting sequence if x [ n ] and the delayed sequence of
(b) above are added together?
