Homework Statement



If you were to generate a square wave with zero offset voltage using a function generater. What shape wave would the V out be if put through an opAmp??




The Attempt at a Solution



For some reason this seems like an odd answer to me, because i want to say a sine wave is the Vout wave produced... but if you were to amplify a square wave wouldn't a bigger square wave be produced? Thants my guess. Thanks!

You shouldn't be guessing at physics problems.

Mathematically, what does a zero offset square wave look like? What does an opamp do to its inputs?
 
The answer to this question depends entirely on what else is connected to the op amp (i.e., resistors, capacitors, etc.).
