Fourier Transform Problem
Just revising my little Fourier Transforms and just realised I don't know how the (Swear) to multiply two expontials together!

The problem is this : Intigral of ( H(t)exp(-at).exp(-jwt) dt.

How would I join these exponentials together, if this is indeed how you do it!

Thanks!(Doh)

$\int H(t)\exp(-at).\exp(-jwt) dt=\int H(t)\exp(-(at+jw)t) dt$
