For the signal \(x (t) = δ(t) – \frac{4}{3} e^{-t} \,u(t) + \frac{1}{3} e^{2t} \,u(t)\). It has how many poles and zeroes at infinity?
(a) 1, 0
(b) 2, 2
(c) 2, 0
(d) 0, 0
This question was addressed to me in unit test.
The doubt is from Average Power and Energy of a Signal in chapter Fourier Series of Signals and Systems
