So if 1.1V=1100mV pp that means it would have a maximum amplitude at 550mV and a minimum amplitude at -550mV.

Yes. What would the DC level be?

 

The DC level would be 23.9V

 

The DC level would be 23.9V

That's correct. So, your output would swing from (23.9 + .55) to (23.9 -.55), right?
Will the output of the 741 do that, given that you have ±9V power supplies?

 

No. It would be limited to 9V

 

No. It would be limited to 9V

That's right. In fact, with a 741 (and many other op amps), the limiting voltage will be substantially below the supply voltage.
As I said in post #12,

That is either a trick problem, or a very poorly designed one.

 

This would be the graph not taking the capacitor into consideration. What effect does the capacitor have?

 

The last opamp is forced against the upper limit by the non-inverting gain on the 1 volt input at the positive input.
The sine wave will cause the output to swing down from the upper limit as the gain of -10 for this side causes the opamp to un saturate.
Remember also that a 741 can not swing up to the upper rail voltage of 9 volts because of the output stage limitation. This case about 7 volts.

 

You can assume this is an ideal op amp and that the voltage can reach 23.9V.

This is apparently homework. Are you saying that you have not covered AC analysis of RC networks in class?

That is wrong.
Did you miss the +1V bias on the +input of the last op amp?

 

No we have not. We are expected to learn everything ourselves.

[soapbox]Where are you a student? Who is paying for your education? If anyone is, they are being ripped off, IMHO. Teachers are supposed to teach, not just tell you what to learn. Learning to do research is a necessary skill, but this is fundamental stuff. It should be explained to you in an interactive environment.[/soapbox]
Ok, now I've gotten that off my chest. Study this and learn from it.

 

Hi,

Thanks for the link. It's very useful.
