I just defined a function like this:

X[\[Omega]_] := 0 /; \[Omega] < 0;
X[\[Omega]_] := 1 /; 0 < \[Omega] < 2;
X[\[Omega]_] := -1 /; 2 < \[Omega] < 4;
X[\[Omega]_] := 0 /; \[Omega] > 4;

Is it possible now to integrate it from -infinity to +infinity? I've
already tried and it doesn't give me the result.
Thanks.

Luca
