[DPRG] encoders signal

I have some surplus encoders, they have two channels with a 40 millivolts
sinusoidal output signal.

I need to use this signal for drive a TTL imput, how can I amplify and
square it?

I suppose to use a OpAmp as a comparator but I'm not able to set the correct
resistor value... :-(

Can someone help me?

Sorry for my bad English, I hope you can understand the problem...
