If you are going to lock them then presumably you have a method of controlling the phase of one. One way of locking them is to use a PLL, can you adjust the frequency of one source (i.e. a VCO)?
In general you need a phase detector, some form of error amplifier / filter / integrator fed back to adjust the phase / frequency of one source. Hard to say more until we know what you have.
I did not understand well that you said but i have two signals with 60 Hz...they are fixed in frequency. I want to start my ramp signal when when the square wave is positive edge triggered.I think phase locking can work for this..Any idea

Here it is ..first one is my reference signal.. second (ramp) one is my input signal...I want it to start at the positive going edge of reference signal..
thank you

Do both of those signals already exist, or do you have one and want to generate the other?
If they both exist, are they at exactly the same frequency? If so, what is their phase relationship?
EDIT: Sorry, I didn't look at your diagram closely before replying. I think it answers my questions.
