Question
The Fourier transform of a function f (x) is defined as:
f (w) = , f(x)e-iax dx
-iwx dx
Similarly, the inverse Fourier transform of a function f (x)
whose Fourier transform is known is found as:
1
f(x) = L f (@) e-iwx dw
So, find the Fourier transform f (w) for a> 0 of the
function given below, and using this result, calculate the
inverse Fourier transform to verify the form f (x) given to
you:
for x > 0
for x < 0
-ах
f (x) = }
