@SunnyskyguyEE75 someone asking a beginner question such as this would clearly not be able to provide the information you asked for. 1.

Overloading someone who is clearly a beginner with too much information with overly technical language than is required is either just to show off your knowledge or intending to confuse.

@SunnyskyguyEE75 If someone asks how to calculate a voltage drop over a resistor, you don't then ask for resistor tolerance, ambient room temperature, input voltage ripple and all sorts of other stuff. You simply say "Ohm's Law". It provides an answer to a simple question without over complicating it.

The easiest way to do this would be to use a comparator.
Picture taken from linked site
All you have to do is set your Vref level to where you want your square wave to trigger. When the sine wave crosses the Vref level, the comparator output will go high. As it approaches it again and goes below the Vref level, the comparator output goes low.
You will then get yourself a square wave.
Be aware the example shown in the graphic is of a non-inverting comparator. An inverting comparator works with the same principle, but the output is inverted

@SunnyskyguyEE75, yes there are. Hence why my opening line was the easiest way. Not the best way. A beginner question deserves a beginners answer. Once the OP has built up knowledge and experience, then better, but more involved ways can be looked at. There is no need to try and belittle my answer by saying there are a dozen better ways just because of what I said in the comments to the question. By all means, write your own overcomplicated answer which I am sure will be useful to more experienced engineers but useless to a beginner

Define peak sine Vp and f tolerances of these variables and tolerance of PW in % of period T=1/f. Can you do that?

@SunnyskyguyEE75 someone asking a beginner question such as this would clearly not be able to provide the information you asked for. 1. That information is not critical to being able to answer and 2. it looks to me like a deliberate attempt to either confuse the OP or to pretty much be a show off. So really, those are pointless requests

Overloading someone who is clearly a beginner with too much information with overly technical language than is required is either just to show off your knowledge or intending to confuse. OP asked how to get a square wave from a sine wave. Simple as that. That is the question that needs to be addressed.

@SunnyskyguyEE75 If someone asks how to calculate a voltage drop over a resistor, you don't then ask for resistor tolerance, ambient room temperature, input voltage ripple and all sorts of other stuff. You simply say "Ohm's Law". It provides an answer to a simple question without over complicating it.
