/* Fourier transform of the input pulse*/ ---> why have to caculate the Fourier transform of the input pulse.

if (T<100) ---->why T have to be smller than 100

for (m=0;m<=2;m++)

{ real_in[m]=real_in[m]+cos(arg[m]*T)*ex[10] --->why have to time ex[10]

imag_in[m]=imag_in[m]-sin(arg[m]*T)*ex[10]

}

thanks a lot
