Hi,

I have this problem and I dont know how to finish it:

Using the Cauchy Theorem, prove that the fourier tranform of1/(1+t^2)is

(pi)*e^(-2*pi*|f|).( you must show the intergration contour) Stetch the power spectrum.

I applied the fourier transform formula but then tried to break down the

1/(1+t^2) but I get stuck to apply the Cauchy theorem.

Please can I have some help?

Thank you

B
