Q: The continuous-time signal f(t) = e^{−2ωt}, where ω is a real constant, is sampled when t ≥ 0 at intervals T. What is the z-transform of the resulting sequence of samples?
(a)z / (z − e^{−2ωT})
(b)z / (1 − e^{−2ωT})
(c)z / (z − e^{−ωT})
(d)z / (z − e^{2ωT})
Correct Answer: (a)
The correct answer is (a): z / (z − e^{−2ωT}). Subject: General Studies | Sub-topic: Miscellaneous Note: This answer was determined through AI-based research. Verify against the official answer key when available.
