Help with circuit

[isabelle]

Hi guys. Hoping some here could help me. Trying to understand how the attached circuit works and im having no luck. Iv got a basic knowledge of the schmitt trigger but thats it. Thanks guys, Isabelle

The first op-amp is a voltage follower with a high input impedance and a low output impedance so its output will be very similar to what the potential divider would give with no load.

The second op-amp is a Schmitt trigger, but you know how that works.

The diagram would be neater if you had a ground line right across the bottom. Moving V3 to the right would take kinks out of the connections. A neat diagram is easier to understand.

Please do not leave the M out of Schmitt.
