Ok..I need some help finding the fourier series components of a modulated rectangular wave.
This is how the func. goes..it is equal to 1 for duration d*Ts and equal to 0 for the duration (1-d)*Ts.i.e it is periodic over Ts.
It would be easy to find the Fourier coefficients if d was a constant...but the big issue is d is modulated.
i.e d itself is a function of time given by
d(t)=D+dmsin(wmt); where dm<<D and wm<ws (ws=2*pi/Ts).
So folks!..How do I go about..someone told me I have to use double fourier series to deal with this.
What the heck is that!..
