Announcements Posted on
Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. Hi i dont know how to find the fourier transform of
δε(t)= ε^-1 if -ε/2<t<ε/2
δε(t)=0 otherwise

any help?
2. is this A-level?

(Original post by DFranklin)
Just use the integral definition.

Just use the integral definition.
4. δ(ω)= integral -ε/2 to ε/2 ε^-1exp(-jωt)dt

just solve the above?
5. Yup.
6. ok thanks!!!
