Convolve expression doesn't produce a result.
a = 0.1; ImpulseResponse[t_] := (1/(2.*Pi*10.*Sqrt[1 - a*a]))*Exp[-a*2*Pi*10*t]*Sin[2.*Pi*10.*Sqrt[1 - a*a]*t] pulse[x_] := Cos[2*Pi*x] Convolve[ImpulseResponse[t], pulse[t], t, x]
I am trying to figure out why and make it work, but I am not really successful at that.
