Can someone figure this out for me? I really don't know where to start. The 1K resistor going up top has me very confused.

The 1k resistor can be considered part of the second stage. Think of the second stage as an inverting summing circuit. Hopefully, this hint will be enough to let you figure this problem out.Can someone figure this out for me? I really don't know where to start. The 1K resistor going up top has me very confused.
OK, so keep the fact that there is positive feedback in mind when you analyze the response of the first stage.Yea that's they way our teacher gave it to us.
You should be able to figure this out. Look at the two nodes that the 1k resistor connects to. One end is a voltage source and the other node is a virtual ground. Ask yourself if the 1k resistor can change these nodes. If so, under what conditions will that happen? Then ask yourself if changes in these nodes can affect the output of the first stage. If so, which node will affect it?So how does the 1K resistor affect the output of the first amplifier?
Yes, you need to become more familiar with the common op-amp configurations and you also need to be able to calculate the response when you encounter configurations you are not familiar with.As you can probably tell, I'm not very confident when it comes to this stuff.
