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

(d) above are added together?
