Sir,I want to plot the spectrum of Amplitude modulation for message signal whose spectrum is a triangular window as shown in the attached link

i.e, I want to plot S(w) , where

and

are entered by the user at run time (i.e, in the Command Prompt window)

My Ideas:

, taking

and proceeding further by applying fourier transform of

will give

, so what should be its code to do so?please help...
