GATE EE 2014 Set 3

MCQ (Single Correct Answer)

-0.3

A signal is represented by $$$x\left(t\right)=\left\{\begin{array}{l}1\;\;\;\left|t\right|\;<\;1\\0\;\;\;\left|t\right|\;>\;1\end{array}\right.$$$ The Fourier transform of the convolved signal y(t)=x(2t) * x(t/2) is

$$\frac4{\omega^2}\sin\left(\frac\omega2\right)\sin\left(2\omega\right)$$

$$\frac4{\omega^2}\sin\left(\frac\omega2\right)$$

$$\frac4{\omega^2}\sin\left(2\omega\right)$$

$$\frac4{\omega^2}\sin^2\left(\omega\right)$$
