hi
i am trying to understand how to convert sine wave to square wave:
i found this over the internet:
**broken link removed**
however i didnt understand some points and i will be happy for explanations:
1. where is connect the second input of the operational amplifier? (i see that it has only one input, however as i know the operational amplifier has 2 inputs)
2. why do we need the capacitor?
thanks alot
