$$x[n] = \frac{3\sin{(3\pi\frac{n}{4})}}{\pi n}$$
What is the Discrete Time Fourier Transform $X(e^{jw})$ of $x[n]$?
Thanks.
I need to plot a graph of $X(e^{jw})$ for the sinc function x[n]. I know it is a rectangular waveform.....

Note that $$\dfrac{\sin \omega_c n}{\pi n}\Longleftrightarrow \text{rect}\left(\dfrac{\omega}{2\omega_c}\right)$$ which is a rectangular function from $-\omega_c$ to $\omega_c$.
