Q: Fourier transform of f(t) = { sin a t, |t| ≤ π ⁄ a ; 0, |t| > π ⁄ a } is
(a)2j sin π ω ⁄ a ⁄ (−a² − ω²)
(b)j sin π ω ⁄ a ⁄ (−a² − ω²)
(c)j sin π ω ⁄ a ⁄ (a² − ω²)
(d)2a j sin π ω ⁄ a ⁄ (ω² − a²)
Correct Answer: (d)
The correct answer is (c): j sin π ω ⁄ a ⁄ (a² − ω²). Subject: General Studies | Sub-topic: Miscellaneous Note: This answer was determined through AI-based research. Verify against the official answer key when available.
