Need Help With - Sine to Square Wave Project

[Zordon]

Hi,

I have a 14VAC transformer and I want to use an op amp to convert a sine wave to square wave at the same frequency as the wall plug. How can i accomplish this with an op amp. I know about differentiators and integrators however I am unsure how to get my op amp to do this.

Thanks

Hi.

I know about differentiators and integrators

Have you heard about comparators?

Start with a "zero crossing detector" followed with some signal conditioning. E
