For the signal x (t) = u (t + 2) . u (t - 2), the value of Fourier transform X (ω) is:
1
\(\frac{{{e^{ - 2j\omega }}}}{{j\omega }} + \pi \delta \left( \omega \right)\)
2
\(\frac{{{e^{ - 2j\omega }}}}{{j\omega }}\)
3
\(\frac{{{e^{ 2j\omega }}}}{{j\omega }} + \pi \delta \left( \omega \right){e^{ - 2j\omega }}\)
4
\(\frac{{{e^{ - 2j\omega }}}}{{j\omega }} + \pi \delta \left( \omega \right){e^{2j\omega }}\)
