inverse fourier transform of a sinc
Numerically?
Sample it, that is generate samples at equally-spaced T values, for a given omega.
omega = 1.0
tMax = 100.0;
tt = linspace(-tMax,tMax,1024).';
s = 2*sinc(omega*tt/pi);![fig.png](https://www.mathworks.com/matlabcentral/answers/uploaded_files/200421/fig.png)

sif = ifft(s);
plot(abs(sif));
grid('on');
You might want to try for different tMax values
