help with homework

[Leond95]

Hi everyone,

please can someone help me with this homework, the question is to find vout and v'out in function of vin and the state of the diods?

The first question is answered easily if you have a basic understanding of op-amps.

What have you figured out so far?

yes i have basic understanding of op-amps but diodes espacially zener diode I forgot about it

When an op-amp is operating normally with negative feedback, what can you say about the two inputs?

If you can't answer this, go back and revise your knowledge of op-amps.

Then go and revise zener diodes. What that does can be answered by one of the implications of the gain of an op-amp (you may want to review that too).
