Find a reference that gives you the relationship between the
spread of a Gaussian time function and the spread of it's
Gaussian Fourier transform. Then find the level at
which you are defining the boundaries of the passband
(e.g., -3dB, -6dB, or -10dB).

The rest should follow more easily.

Hope this helps.
