Hii I have a sine wave of freq 50 Hz stepped down from a transformer and a triangular wave generated from IC8038 with freq 3KHz now i have to synchronize these two waves so that my pulse width modulation wave obtained from these two waves on inputing to a comparator has a quarter wave symmetry.

Please HELP!!!!!

You won't achieve sync, ever, unless you go for a phase-lock circuit.
 

and what's that can u tell me how to make a phase-lock circuit any tutorial or even circuit diagram
and will it guarantee syn?
