Use UnitStep to define g i.e., g = t(UnitStep[t] - UnitStep[t - 1]) + (1.5 - .5 t)(UnitStep[t - 1] - UnitStep[t - 3]) then you can do Plot[g, {t,-1,4}, PlotRange->All]; to plot the function and FourierTransform[g, t, w] to get the Fourier transform -- To reply via email subtract one hundred and four
